Otimização por Colônia de Formigas
Introdução

Baseado no comportamento das formigas para
 busca de alimento;
Necessita de mapeamento por grafo do espaço
 de busca;
Formigas podem trabalhar no modo foward
 (indo da colônia para o alimento) ou backward
 (voltando do alimento para a colônia)
Formigas Foward

Escolhe probabilisticamente o próximo vértice
 para se mover entre os vizinhos no grafo onde
 o no esta localizado. A escolha é guiada pelas
 trilhas de feromônios depositadas
 anteriormente no grafo por outras formigas no
 modo backward. As formigas que estao no
 modo “forward” nao depositam nenhum
 feromônio enquanto estao se movimentando.
Formigas backward

Na volta da solução encontrada (comida) para a
 colônia (ponto de partida), a formiga deve
 depositar feromônio de acordo com o critério
 do que se considera uma boa solução.
Adaptação

Na aplicação para buscar soluções para a
 função zeta os nós vizinhos da formiga são
 gerados em tempo de execução (já que não é
 possível mapear todo o conjunto dos
 complexos);
Além disso o feromônio é dado pela proporção
  inversa com a imagem da função zeta no
  numero complexo dado;
Adaptação

Enfim, foi necessário acrescentar como critério
 de decisão, além do feromônio, a imagem da
 função no ponto testado pela formiga (para
 evitar loops).
