Harvard CS50 AI Week 0: Search — From DFS, BFS, A* to Minimax and Alpha-Beta Pruning

Week 0 opens with search algorithms: BFS for shortest paths, Minimax for adversarial play, Alpha-Beta for pruning. Two projects: Degrees (BFS) and Tic-Tac-Toe (Minimax).

CMU 07-280 Lecture 3: Minimax, Alpha-Beta, and Expectimax

Lecture 3 turns a single path into a contingent plan: minimax faces an optimal opponent, alpha-beta skips branches without changing the root value, and expectimax replaces worst-case choice with probability.

CS188 CSPs and Multi-Agent Search: Choosing Minimax, Alpha-Beta, and Expectimax

Lectures 5–8 use CSPs to practice variables, constraints, and search order before Project 2 implements minimax, alpha-beta, and expectimax. Their key difference is the assumption made about other agents.

2026 Q1 Open-Source LLM Landscape: From Frontier Models to On-Device, a Complete Survey

2026 Q1 saw a full-blown open-source model explosion: on the LLM front, GLM-5, Kimi K2.5, and Qwen3.5 caught up with closed-source models; Embedding and Reranker are dominated by Qwen3 and BGE; speech has Voxtral TTS and Whisper V3; image has FLUX.2; and video has Wan 2.2 rivaling Sora. This is the complete navigation map.
