PSEUDOCÓDIGO
1. Faça todas as células = ∞
2. Faca a célula atual = 0
3. Faça para todas as células passáveis:
3.1. Célula atual = min(célula, célula_vizinha + 1)
3.2. Se célula_destino ≠ ∞
3.2.1. Vá para passo 4
3.3. Caso contrário
3.3.1. Vá para passo 3
4. Fim
A*
G: custo para se mover para a célula (cumulativo)
H: heurística
F: G + H
Open_list: células a serem analisadas
Closed_list: células já analisadas
Início
Fim
Open_list: células a serem analisadas
Closed_list: células já analisadas
PSEUDOCÓDIGO
1. Coloque a célula inicial na open_list
2. Para a célula com menor F da open_list, faça:
2.1. Transfira-a para a closed_list
2.2. Para suas células vizinhas passáveis:
2.2.1. Calcule seus custos e acrescente-a na open_list,
caso ainda não esteja
2.2.2. Se já estiver, verifique os custos, atualizando caso
necessário
2.3. Se a célula destino estiver na closed_list ou a open_list
esteja vazia
2.3.1. Vá para passo 3
2.4. Caso contrário
2.4.1. Vá para passo 2
