Talvez deva tentar algumas variações de ortografia:
protocol python » protocol method (Expandir a busca), protocol without (Expandir a busca), protocol methods (Expandir a busca)
age programming » agent programming (Expandir a busca), stage programming (Expandir a busca), agile programming (Expandir a busca)
based protocol » and protocol (Expandir a busca)
decrease age » decrease the (Expandir a busca), decrease and (Expandir a busca), decrease akt (Expandir a busca)
python based » action based (Expandir a busca)
decrease of » decrease in (Expandir a busca)
of decrease » not decrease (Expandir a busca), to decrease (Expandir a busca), of decree (Expandir a busca)

Você pode obter mais resultados ajustando o argumento de busca.

• Remover as aspas pode possibilitar buscas mais amplas: (( decrease of decrease age programming ) OR ( python based protocol python programming ))~.
