Homework Guidelines

Formatting homework.

You can write your homework in one of the following ways:

• Typeset your answers using LaTeX. We strongly recommend doing this. See the Latex Guide for help using LaTeX.
• Type your answers using a mainstream word processor.
• Neatly handwrite, then use a flatbed scanner or smartphone app (such as CamScanner) to produce a PDF. Do not simply take a photo and dump it into a PDF.

The readers work hard to grade your homeworks in a timely manner, and with useful feedback. Given the size of the course, we require a certain format of all homeworks: each problem must start on a new page, and clearly display the problem number; if a problem has multiple parts, make sure that each part fits on a page. You must also select the pages for each problem when you submit to Gradescope, if you do not do this, you may not get points on that problem .

List your collaborators on the first page of your submission. If you have no collaborators, you must explicitly write “none”.

Three-Part Algorithm Format

Oftentimes, a problem will ask you to “give/design/devise/formulate/create/etc. an algorithm” or to “show how” to solve some computational task. In this case, write your solution in the 3-part algorithm format:

• Your pseudocode does not need to be executable. You should use notation such as “add X to set S ” or “for each edge in graph G”. Remember you are writing your pseudocode to be read by a human, not a computer.
• See DPV for examples of pseudocode.
• Again, see DPV for examples of proofs of correctness.
• Runtime analysis . You should use big-O notation for your algorithm’s runtime, and justify this runtime with a runtime analysis. This may involve a recurrence relation, or simply counting the complexity and number of operations your algorithm performs.

Solo Problems

Some problems on the homework may be labelled as solo problems . These problems are written to be easier than “standard” homework problems, but you are not allowed to collaborate with other students on these problems. You are still allowed to consult staff, e.g, at office hours for help on these problems, and staff can still answer questions about these problems to groups of people at office hours (though you should avoid discussing them at office hours while waiting for staff to get to you). The goal of these problems is to give yourself a benchmark for how well you would do if a similar problem appeared on an exam.

When I have to write an algorithm, how should I format my answer?

We will do our best to specify what we expect you to write in each question, but when in doubt, default to a “3-part” solution, which is discussed here .

How efficient does my algorithm need to be?

Do your best. We may or may not give a running time requirement up-front (sometimes that would give a strong hint on how to do the problem). Some baseline considerations: Most problems have a natural naive/brute-force algorithm (e.g. “try all possibilities”) or other trivial approaches (e.g. “apply [suboptimal known algorithm] without any modification or thought”). These usually receive no credit. Exponential-time algorithms usually get no credit. We often award partial credit to algorithms that are slower than our official solutions.

Can I cite theorems and algorithms from the textbook or lecture without proof?

Can I use theorems and algorithms from other sources?

As detailed in the syllabus, you should not look up problem solutions using the internet/other sources. If you do run into a useful theorem/algorithm that aids in your solution, (a) you must prove it in your solution and (b) make sure to cite the source you got it from.

Is my interpretation of the problem correct? What about such-and-such case?

Piazza is not a good forum to figure out what a problem is asking / ask for hints or confirmation. Even something as innocuous as, “So on x input we would return y solution, correct?” can reveal a lot about a problem, which hurts other students’ understanding. Please first try asking fellow students and coming to office hours. If after doing this you still believe the problem is poorly worded and genuinely ambiguous, please go ahead and explain the ambiguity, but we will tend to avoid answering such questions when the problem is not unclear. Much of the challenge of the problem sets is precisely understanding the nuances of the problem, and asking to be given all the details defeats that purpose.

Do we give our algorithm’s worst-case running time, or average running time?

Most algorithms in this course are deterministic ones, for which we are always concerned with the worst case. For randomized algorithms, the expected running time is acceptable. Note that this may receive less credit if a superior deterministic algorithm is known.

Do I have to give Θ(⋅) running times for my algorithms, or only O(⋅)?

If it is possible to provide a \(\Theta(\cdot)\) bound in a simple manner, then you should do so. If it is not, then give the tightest \(\mathcal{O}\) bound possible.

What’s the deal with Θ(⋅) vs O(⋅) notation anyways?

We try to stick with the actual definitions, which means to use \(\Theta(\cdot)\) notation when you’re describing the exact asymptotic runtime. However, the textbook often uses \(\mathcal{O}(\cdot)\) notation even when giving tight bounds; if in the above example you wrote \(\mathcal{O}(n)\) for the runtime, we would still give you full credit because the runtime was correct, even though it’s better practice to use \(\Theta(\cdot)\) notation.

Can I make reasonable assumptions about the computational model?

Yes. If you think the assumption is not totally obvious, feel free to explain it as you perform the runtime analysis (eg “Because indexing into arrays takes constant time, …”)

Can I make [some additional assumption] about [some homework problem] that was not given in the problem?

No. For example, don’t assume numbers in a list are distinct, don’t assume a graph is connected, etc.

Do I need to provide a justification for my answer?

Yes, unless the problem explicitly states that justification is not required.

How rigorous does my explanation need to be?

Rigorous enough for any average CS170 student to understand it completely.

Can I use things shown in discussion/lecture/textbook without proof?

General response to this is: you are free to use things shown to you in lecture/textbook/discussion without proof, within bounds. The “within bounds” means that be reasonable with us — if we ask you to show that \(\sum_{k=1}^n k = \Theta(n^2)\), don’t say “This was shown in discussion so it is true.” Don’t take away the heart of a problem and claim it was done in X, that’s being too clever for your own good and won’t fare well. We expect students to be able to reason about what “within bounds” means. So feel free within bounds. And if in doubt about anything — ask.

How will homework be graded?

Homework will be graded as a mix of coarsely and finely graded parts. (Some problems may be graded on a 100%, 50%, 0% scale, while others may be graded more carefully and finely.) An unannounced, not necessarily strict, subset of problems will be graded each week. Points will be assigned to problems after students have submitted the homework.

According to a recently published study, people who only get six or seven hours of sleep have longer life (26)_______ than those who sleep eight or more hours. “The idea that we need eight hours of sleep is completely unscientific,” said Professor Daniel Kripke, who led the study. The methods used, (27) _______ , have been criticised. Investigators relied on people's own accounts of how long they slept, (28) _______ could be rather imprecise, as no one really knows when they fall asleep. Contrary to Professor Kripke's findings, (29) _______ experts believe that getting insufficient sleep is a serious problem. What all scientists agree on is that more research is needed to discover exactly what the relationship is between sleep and longevity. This research is essential because with all the (30) _______ of modern life, such as cable TV and the Internet, it seems that a good night's rest is becoming increasingly rare.

Read the following passage and mark the letter A, B, C, or D on your answer sheet to indicate the correct answer to each of the questions from 31 to 35.

Going to the gym or the sports centre often feels like a joyless necessity. The sweaty rooms and irritating music seem to be part of the price you pay for getting fit. In actual fact, your exercise routine will have some bad side-effects and we don't just mean aching muscles! Gyms and sports centres need huge amounts of energy for lights, air conditioning, heating - and of course, pools and machines. Luckily, there's now another way for people who care about more than calorie-counting. Green Fitness allows you to exercise in the open air, surrounded by birdsong. What's more, rather than destroying the planet, you'll be helping to preserve it. How? By doing conservation work in some of the most beautiful parts of the country. If you've never done any gardening before, don't worry. We'll give you all the training you need. Volunteers cooperate to achieve tasks together, so you won't be on your own. The team spirit is amazing- something which you're never going to find at the gym! What's more, many volunteers have reported that taking part in sessions has boosted their self-esteem and happiness. However, this is not a 'soft' alternative and laziness is not an option! An hour's moderate gardening is at least as demanding as a six-kilometre jog and builds strength in all parts of your body.

Read the following passage and mark the letter A, B, C, or D on your answer sheet to indicate the correct answer to each of the questions from 36 to 42.

Welcome to Nunavik - a beautiful landscape of forests, blue skies and clear waters. You might think that Nunavik's geographical position at the ends of the Earth keeps it safe from big city problems like air and water pollution. Unfortunately, the pretty villages of Nunavik have not escaped the problems that the rest of the world is facing, too. Some years ago, scientists made a worrying discovery. An extremely dangerous group of chemicals known as 'persistent organic pollutants' (or POPs) were attacking the Arctic environment. POPs are used everywhere - in TVs, in lights and in paint. They are also sprayed onto crops as pesticides. Over time, they become gas and go into the air, and the wind carries them thousands of kilometres. POPs can cause cancer and allergies, as well as other damage. They can also cause developmental problems in babies and children. Clearly, something had to be done about the problem and so in the 1990s, the United Nations held a meeting called the Stockholm Convention to discuss banning lots of the POP chemicals. Since then, many countries have agreed to start producing fewer POP chemicals, and as a result, levels of POPs in the Arctic are falling . It will take many years for the problem to go away. For one thing, buildings around the world still have many tons of POPs in their paint and wiring. For all the people and animals in the Arctic regions, their only hope is the work of scientists and the help of the rest of the world in putting an end to POPs once and for all.

APARTMENT IN MOSCOW

Architects: M17 Location: Kazarmennyy pereulok, 3, Moskva , Russia, 109028 Design Team: A. Volkov, E. Vinogradova Area: 158.0 sqm Year: 2014 Photographs: Courtesy of A.Volkov

The apartment is located in the downtown area of Moscow. General concept of this apartment is to bring the natural landscape inside the interior living environment. The owner is a dzen buddist.

We tried to use less partitions and walls for zoning the space to avoid the closeness, to make it more spacious and opened, without compromising functionality. We used the principle of traditional Japanese house.

This apartment building was built a view years ago, so the first sight was just among the concrete labyrinth. But the natural concrete texture was great and it was the first material we had chosen.

Thus the main polygonal wall appeared: this 20-meter long curved surface goes through all the open-space zone: entrance hall, tea room, garden, kitchen & dining zone. It takes all the technical stuff, store rooms, built-in kitchen, laundry room, wardrobe and guest bathroom.

All these utility zones are hidden from a view, leaving only pure open space. Polygonal segments depicts the roughness of a natural stone, as a mountain fragment.

The emotional point of this apartment is a garden. It locates in the center zone. Bathroom zone was also made from simple natural materials – marble and old wooden planks. Living room devides into tearoom and guestroom.
