Talvez deva tentar algumas variações de ortografia:
estimation algorithm » estimation algorithms (Expandir a busca), optimization algorithm (Expandir a busca), realization algorithm (Expandir a busca)
initial estimation » interval estimation (Expandir a busca), initial formation (Expandir a busca), initial education (Expandir a busca)
algorithm in » algorithms in (Expandir a busca), algorithm ii (Expandir a busca), algorithm on (Expandir a busca)
activity and » activity based (Expandir a busca), activity of (Expandir a busca)
in activity » main activity (Expandir a busca), _ activity (Expandir a busca), brain activity (Expandir a busca)
routine in » routines in (Expandir a busca), routing in (Expandir a busca), routine and (Expandir a busca)

Você pode obter mais resultados ajustando o argumento de busca.

• Fazer uma busca fuzzy pode resultar em termos de grafias semelhantes: routine in initial estimation algorithm in activity and python computer~.
• Caso esteja tentando utilizar os operadores booleanos, deve escrevê-los em Letras MAIÚSCULAS: routine in initial estimation algorithm in activity AND python computer.
• Adicionar um caractere curinga pode recuperar variações da palavra buscada: routine in initial estimation algorithm in activity and python computer*.
