Talvez deva tentar algumas variações de ortografia:
estimation algorithms » optimization algorithms (Expandir a busca), optimization algorithm (Expandir a busca), approximation algorithms (Expandir a busca)
activity estimation » activity estimates (Expandir a busca), activity elicitation (Expandir a busca), activity evaluation (Expandir a busca)
algorithms general » algoritmo general (Expandir a busca), algorithms neural (Expandir a busca), algorithms genetics (Expandir a busca)
decrease activity » disease activity (Expandir a busca), urease activity (Expandir a busca), redutase activity (Expandir a busca)
general method » energy method (Expandir a busca), generalized method (Expandir a busca)

Você pode obter mais resultados ajustando o argumento de busca.

• Adicionar um caractere curinga pode recuperar variações da palavra buscada: decrease activity estimation algorithms general method*.
