1. 使用聰明狗 A*模胚，模擬聰明狗 A* 每個情境的動畫

All nodes of A* tree manually simulated

2. 續上題，依據決策樹自動模擬每個情境

All nodes of decision tree auto fully simulated

3. 提升美學與完成度，進入v1從這裡開始

boot up

4. Solve for the gain.  Then Frequency response. (講義)

參考解答

Gemini 2.5 Pro for 2-stage amp, Freq Response

Claude Sonnet 4.5 Freq resp (all in one) vs. staged

staged calculation leads to better, more accurate results.

plot bode plot gain vs. Hz from staged computation

plot bode plot phase vs. Hz

任選兩題

1. 推理模式 special topic Smart Dog Ball Retrieval 

Given resources as below

• Build an animation of A* search tree (artifact) based on A* template
• more complete and more aesthetic

Examples: 

• Noodle +  Wave
• Noodle + blue pool 

• boot up

• backtrack

• All nodes of A* tree manually simulated, share (Data visualization techniques)
• All nodes of decision tree auto fully simulated, share (Full Demo)

Build A* search animation

 

A* search tree animation in detail

Advanced visualization with backtrack included and transit animated (Data visualization techniques) 

note:  Under A* search heuristics,  backtracking does not happen in this case. Therefore, "backtracking" here is a borrowed concept. Tree may not be accurate as Sarah is left out on the goal path.
