Talvez deva tentar algumas variações de ortografia:
based programming » and programming (Expandir a busca), based program (Expandir a busca), cone programming (Expandir a busca)
decrease based » decreased base (Expandir a busca), decrease blood (Expandir a busca)
tests python » reais python (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)
python code » python coding (Expandir a busca), python redes (Expandir a busca)
code tests » score tests (Expandir a busca), cloze tests (Expandir a busca), clone tests (Expandir a busca)

Você pode obter mais resultados ajustando o argumento de busca.

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