Talvez deva tentar algumas variações de ortografia:
formation algorithm » formulations algorithms (Expandir a busca), estimation algorithm (Expandir a busca), forming algorithm (Expandir a busca)
spatial formation » initial formation (Expandir a busca), social formation (Expandir a busca), spatial variation (Expandir a busca)
main activity » human activity (Expandir a busca), dairy activity (Expandir a busca), abc activity (Expandir a busca)
theory python » the python (Expandir a busca), theory method (Expandir a busca)
routine and » routines and (Expandir a busca), routing and (Expandir a busca), routine care (Expandir a busca)
in activity » _ activity (Expandir a busca), brain activity (Expandir a busca), high activity (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 spatial formation algorithm ((in activity) OR (main activity)) theory python computer~.
• As palavras AND, OR e NOT pode ocasionar problemas na busca; tente utilizar as aspas: "routine and spatial formation algorithm ((in activity) OR (main activity)) theory python computer~".
• Adicionar um caractere curinga pode recuperar variações da palavra buscada: routine and spatial formation algorithm ((in activity) OR (main activity)) theory python computer*.
