Algorithms

CSE221

Sorting, graph traversal, shortest paths, spanning trees and dynamic programming.

Compare g, h and f at every expansion to see why A* beats plain Dijkstra on a grid.

CSE422

Search, game trees and the arithmetic behind learning.

Compare BFS, DFS, uniform cost and greedy heuristic search on one search tree.

Propagate values up a two-player game tree and see which move each level picks.

Watch alpha and beta tighten and see exactly which branches get cut off, and why.

Split a small dataset on each feature and compare entropy and information gain.

Step through gradient descent as error and learning rate move each weight.

Move the decision threshold and watch TP, FP, TN, FN, precision and recall react.
