Talvez deva tentar algumas variações de ortografia:
formulations python » formulations on (Expandir a busca), formulations with (Expandir a busca), formulations to (Expandir a busca)
based formulations » based simulation (Expandir a busca)
python codigo » python coding (Expandir a busca), python code (Expandir a busca)
coder python » compra python (Expandir a busca)
python based » action based (Expandir a busca)
coder coder » coder decoder (Expandir a busca), code code (Expandir a busca), decoder codec (Expandir a busca)

Você pode obter mais resultados ajustando o argumento de busca.

• Remover as aspas pode possibilitar buscas mais amplas: (( coder coder python codigo python ) OR ( python based formulations python programming ))~.
