Talvez deva tentar algumas variações de ortografia:
variation algorithm » realization algorithm (Expandir a busca), adaptation algorithm (Expandir a busca), estimation algorithm (Expandir a busca)
spatial variation » seasonal variation (Expandir a busca), spatial organization (Expandir a busca)
algorithm using » algorithms using (Expandir a busca), algorithm design (Expandir a busca)
using activity » nursing activity (Expandir a busca), buying activity (Expandir a busca), guiding activity (Expandir a busca)
routines and » routing and (Expandir a busca), routes and (Expandir a busca), routines in (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.

• Fazer uma busca fuzzy pode resultar em termos de grafias semelhantes: routines and spatial variation algorithm using activity in python computer~.
• Caso esteja tentando utilizar os operadores booleanos, deve escrevê-los em Letras MAIÚSCULAS: routines AND spatial variation algorithm using activity in python computer*.
