Talvez deva tentar algumas variações de ortografia:
estimation algorithms » optimization algorithms (Expandir a busca), optimization algorithm (Expandir a busca), approximation algorithms (Expandir a busca)
building estimation » building automation (Expandir a busca), building estimates (Expandir a busca), bunching estimation (Expandir a busca)
programming python » programming method (Expandir a busca), programmation python (Expandir a busca), programacao python (Expandir a busca)
java building » and building (Expandir a busca), tall building (Expandir a busca), car building (Expandir a busca)
on python » in python (Expandir a busca), _ python (Expandir a busca), piton python (Expandir a busca)
of python » _ python (Expandir a busca), in python (Expandir a busca), of pathos (Expandir a busca)

Você pode obter mais resultados ajustando o argumento de busca.

• As palavras AND, OR e NOT pode ocasionar problemas na busca; tente utilizar as aspas: "java java building estimation algorithms ((on python) OR (of python)) programming python computer~".
• Adicionar um caractere curinga pode recuperar variações da palavra buscada: java java building estimation algorithms ((on python) OR (of python)) programming python computer*.
