Talvez deva tentar algumas variações de ortografia:
optimization algorithm » optimization algorithms (Expandir a busca)
semantic optimization » static optimization (Expandir a busca), kinematic optimization (Expandir a busca), demands optimization (Expandir a busca)
algorithm in » algorithms in (Expandir a busca), algorithm ii (Expandir a busca), algorithm on (Expandir a busca)
routines in » routing in (Expandir a busca)
in semantic » on semantic (Expandir a busca), and semantic (Expandir a busca), non semantic (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.

• Fazer uma busca fuzzy pode resultar em termos de grafias semelhantes: routines in semantic optimization algorithm in activity in python computer~.
• Adicionar um caractere curinga pode recuperar variações da palavra buscada: routines in semantic optimization algorithm in activity in python computer*.
