What a finished CSC-FPX4020 Assessment 1 complexity analysis looks like
The finished analysis looks like mathematics attached to code. Each algorithm under examination appears first as the code itself, then as a count: which operation dominates, how many times the loops execute it as the input grows, and what that growth simplifies to. Nested iterations get multiplied out visibly, and where recursion is involved, the recurrence is written down and solved on the page rather than answered from a table. Beside every worst-case bound sits the input that causes it, constructed and described, because a bound without its adversarial input is an assertion. Space gets the same treatment as time, including what the recursion stack quietly consumes. The prose between derivations explains decisions, and a reader who disagrees can point to the exact step where.
How a CSC-FPX4020 Assessment 1 example is structured
The example handles each algorithm in the same four-part rhythm, which is what makes it easy to grade. The code comes first, small and commented. The time derivation follows, working from the innermost operation outward: cost per execution, executions per loop, loops per call, ending in a bound with the dominant term named and the discarded terms listed. The worst-case construction comes third, building the specific input that makes the bound tight, a sorted array fed to the wrong pivot rule, a key that collides repeatedly, and walking a few iterations to show the cost accumulating. Space analysis closes each block, counting allocations and stack depth. Between blocks, the paper compares the algorithms on the bounds just derived, and the conclusion states which growth rates the problem can tolerate at realistic input sizes. Presentation follows the scoring guide's order of criteria.
Bounds derived, never quoted
Every complexity result comes out of counting the code's own operations, because a figure copied from a reference table is an answer with no work attached.
The worst case built by hand
The example constructs the exact input that forces each bound, which proves the analysis understands the algorithm rather than remembering its reputation.
Recurrences set up and solved
Recursive costs are expressed as a recurrence and worked to a closed form on the page, since asserting the result skips the graded reasoning.
Space counted alongside time
Allocations, auxiliary structures and stack depth get their own accounting, because space complexity is the half of the analysis papers most often forget.
Discarded terms listed openly
The simplification from full count to dominant term is shown, so a reader sees what the big-O notation absorbed and why that is legitimate.
Where marks go in CSC-FPX4020 Assessment 1
This is an assessment where wrong exists. A stated bound that the code does not produce is marked as an error, not a weak argument, and no surrounding prose recovers it. The larger and quieter loss is the right answer with no derivation: in many sections a bound with no visible steps is read as work never done, so a correct result arrives at Basic because the reasoning it needed never appeared. Worst cases asserted without a constructing input are a third leak, and average-case figures presented as guarantees a fourth. Space analysis goes missing in a large share of submissions, taking its criterion with it. Distinguished work is distinguished mostly by completeness: every bound derived, every worst case built, every simplification justified, and one honest sentence where the analysis rests on an assumption.

CSC-FPX4020 Assessment 1 questions, answered
What does a derivation actually look like in this paper?
A count a reader can follow: the operation that dominates, the number of times each loop runs it in terms of n, the multiplication across nesting, and the simplification to the leading term. For recursion, it is the recurrence and its solution. If a classmate could check each line and find the exact step they dispute, you have written one.
Do I need worst, best and average case for every algorithm?
Follow your instructions, but the worst case with its constructing input is the piece scoring guides in this course consistently expect. Best case is usually cheap to add. Average case is the one to handle carefully, because it depends on an input distribution you have to state, and an average claimed without one is exactly the kind of unsupported figure this assessment penalizes.
Can my final bound be wrong but still earn credit?
Partial credit lives in the visible work. A derivation with one slip in the counting still shows the method, and in many sections the criteria award the reasoning separately from the result. An unsupported bound offers nothing to salvage in either direction. Deriving carefully, then sanity-checking the result against a small traced input, protects you on both ends.
