Talvez deva tentar algumas variações de ortografia:
optimize estimation » optimal estimation (Expandir a busca), cognitive estimation (Expandir a busca)
time estimation » the estimation (Expandir a busca), state estimation (Expandir a busca), pose estimation (Expandir a busca)
algorithm in » algorithms in (Expandir a busca), algorithm ii (Expandir a busca), algorithm on (Expandir a busca)
routine and » routines and (Expandir a busca), routing and (Expandir a busca), routine care (Expandir a busca)
in activity » main activity (Expandir a busca), _ activity (Expandir a busca), brain activity (Expandir a busca)
activity in » activity and (Expandir a busca), activity of (Expandir a busca)
in python » via python (Expandir a busca), _ python (Expandir a busca), of python (Expandir a busca)

Você pode obter mais resultados ajustando o argumento de busca.

• Caso esteja tentando utilizar os operadores booleanos, deve escrevê-los em Letras MAIÚSCULAS: routine AND ((optimize estimation) OR (time estimation)) algorithm in activity in python computer~.
• As palavras AND, OR e NOT pode ocasionar problemas na busca; tente utilizar as aspas: "routine and ((optimize estimation) OR (time estimation)) algorithm in activity in python computer~".
• Adicionar um caractere curinga pode recuperar variações da palavra buscada: routine and ((optimize estimation) OR (time estimation)) algorithm in activity in python computer*.
