In the following, f is the evaluation function used in the A* search, h is the heuristic function, g is the path cost of a node and c is the step cost from a parent node to a child node. Nodes 𝑛𝑛2 and 𝑛𝑛4 are along the optimal path to the optimal goal node 𝐺𝐺1. Leaf nodes 𝐺𝐺2 and 𝐺𝐺3 are suboptimal goal nodes. (a) 𝑓𝑓(𝐺𝐺2) ≥ 𝑓𝑓(𝐺𝐺1) (b) 𝑔𝑔(𝑛𝑛5) ≥ 𝑔𝑔(𝑛𝑛7) (c) 𝑐𝑐(𝑛𝑛6, 𝐺𝐺3) ≥ ℎ(𝑛𝑛6) (d) 𝑔𝑔(𝐺𝐺1) ≥ 𝑓𝑓(𝑛𝑛4) (e) 𝑓𝑓(𝑛𝑛3) ≤ 𝑓𝑓(𝐺𝐺1)
