Talvez deva tentar algumas variações de ortografia:
approximation algorithm » approximation algorithms (Expandir a busca), propagation algorithm (Expandir a busca)
vector approximation » best approximation (Expandir a busca), dct approximation (Expandir a busca), et approximation (Expandir a busca)
to plasticity » of plasticity (Expandir a busca), food plasticity (Expandir a busca), soil plasticity (Expandir a busca)
algorithm to » algorithm _ (Expandir a busca), algorithms _ (Expandir a busca)
routine and » routines and (Expandir a busca), routing and (Expandir a busca), routine care (Expandir a busca)
and vector » and reactor (Expandir a busca), in vector (Expandir a busca), and vectorial (Expandir a busca)
and python » in python (Expandir a busca), usando 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: routine and vector approximation algorithm to plasticity and python computer~.
• Caso esteja tentando utilizar os operadores booleanos, deve escrevê-los em Letras MAIÚSCULAS: routine AND vector approximation algorithm to plasticity AND python computer*.
