CSE 332 Winter 2014 Final Exam: March 17, 2014. Two final exams will be offered. Students may choose to attend one offering.
4:30-6:20pm and 6:30-8:20pm
The final will be in JHN 102 (NOT one of our regular classrooms)
- Exam policies
- Closed book, closed notes, no calculators allowed.
- The first exam begins promptly at 4:30 and ends at 6:20.
- The second exam begins promptly at 6:30 and ends at 8:20.
- The final will focus on all material studied since the midterm.
This is roughly: Sorting, Graphs, Parallelization, Concurrency,
- Check the lecture calendar for links to all slides and ink used
in class, as well as readings for each topic.
- Note that the material in this course tends to build on itself,
so it would also be reasonable to expect you to remember the basics
of data structures covered earlier in the quarter or what big-O
etc. means. I will not ask you to actually *do* an AVL insertion or
a B-tree insertion/deletion, but having a reasonable idea of how
these work would be a good idea.
Topics (not necessarily an exhaustive list):
- Simple Sorts: Insertion Sort, Selection Sort
- Heap Sort
- Merge Sort
- Quick Sort
- Bucket Sort & Radix Sort
- Know run-times
- Know how to carry out the sort
- Lower Bound for Comparison-based Sorting
- Won't be asked to give full proof
- But may be asked to use similar techniques
- Be familiar with the ideas
- Graphs - In general, know how to carry out the operation/algorithm & running time.
- Graph Basics
- Definition; weights; directedness; degree
- Paths; cycles
- Graph Representations
- Adjacency List
- Adjacency Matrix
- What each is; how to use it; pros and cons of each.
- Graph Traversals
- What data structures are associated with each?
- Topological Sort
- Dijkstra's Algorithm for Finding Shortest Paths
- Disjoint Union-Find
- Kruskal's Algorithm for Finding Minimum Spanning Trees
- ForkJoin Parallelism, and Associated Terms (Work, Span, etc.)
- ForkJoin Applications, ex: Parallel Summing of an Array
- Be able to write pseudo-code
- Reduce: parallel sum, multiply, min, find, etc.
- Map: bit vector, string length, etc.
- Parallel Prefix Sum Algorithm, Filters, etc.
- Analysis of Parallel Algorithms
- Parallel Sorting
- Amdahl's Law
- Race Conditions
- Data Races
- Synchronizing your code
- Locks, Reentrant locks
- Java's synchronize statement
- Readers/writer locks
- Issues of critical section size
- Issues of lock scheme granularity coarse vs fine
- Knowledge of bad interleavings
- Be able to write pseudo-code for Java threads & locks
- Amortized Analysis
- Difference between amortized and worst case performance
- Why amortized analysis is useful
Stuff that you will NOT be tested on:
- Java syntax
- Note that you WILL likely be required to write Java code (in
particular Fork-Join or Java thread code), but we will not be
sticklers for Java syntax. Edge cases and other details of a
correct algorithm - yes, semicolons - no.
- Writing a simple proof of some sort is a possibility. Any such
proof will be intended to show that you know how to prove
things. You will not be expected to have a "magic insight" in the
course of the proof.
- The homeworks are a decent indication of the types of
questions that could be asked
This quarter's final will be along the same general lines as 332
final exams from previous quarters. Our hope is that these exams will be
useful in your studying, HOWEVER you should not take them as a guarantee
of exactly what your exam will be like this quarter.
