Talvez deva tentar algumas variações de ortografia:
estimation methods » evaluation methods (Expandir a busca)
code estimation » coke estimation (Expandir a busca), core estimation (Expandir a busca), mode estimation (Expandir a busca)
code decrease » oxide decrease (Expandir a busca), roads decrease (Expandir a busca), to decrease (Expandir a busca)
python python » pythons python (Expandir a busca), piton python (Expandir a busca), pitons python (Expandir a busca)
methods code » methods ode (Expandir a busca), methods core (Expandir a busca), methods model (Expandir a busca)

Você pode obter mais resultados ajustando o argumento de busca.

• Remover as aspas pode possibilitar buscas mais amplas: (( code estimation methods code decrease ) OR ( _ python python python programming ))~.
