Talvez deva tentar algumas variações de ortografia:
estimation algorithms » optimization algorithms (Expandir a busca), distribution algorithms (Expandir a busca), optimization algorithm (Expandir a busca)
neural estimation » neural stimulation (Expandir a busca), delay estimation (Expandir a busca), energy estimation (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)
in activity » _ activity (Expandir a busca), brain activity (Expandir a busca), high activity (Expandir a busca)
and neural » and natural (Expandir a busca)
routing » routine (Expandir a busca), routines (Expandir a busca)

Você pode obter mais resultados ajustando o argumento de busca.

• Fazer uma busca fuzzy pode resultar em termos de grafias semelhantes: routing and neural estimation algorithms ((in activity) OR (main activity)) theory python computer~.
• Caso esteja tentando utilizar os operadores booleanos, deve escrevê-los em Letras MAIÚSCULAS: routing AND neural estimation algorithms ((in activity) OR (main activity)) theory python computer.
• As palavras AND, OR e NOT pode ocasionar problemas na busca; tente utilizar as aspas: "routing and neural estimation algorithms ((in activity) OR (main activity)) theory python computer".
• Adicionar um caractere curinga pode recuperar variações da palavra buscada: routing and neural estimation algorithms ((in activity) OR (main activity)) theory python computer*.
