Talvez deva tentar algumas variações de ortografia:
observed programming » oriented programming (Expandir a busca), based programming (Expandir a busca), bilevel programming (Expandir a busca)
decrease observed » case observed (Expandir a busca), decay observed (Expandir a busca)
in decrease » in decreased (Expandir a busca), on decrease (Expandir a busca), pain decrease (Expandir a busca)
python code » python coding (Expandir a busca), python redes (Expandir a busca)
data python » dado python (Expandir a busca), gate python (Expandir a busca), dados python (Expandir a busca)
code data » wide data (Expandir a busca), barcode data (Expandir a busca)

Você pode obter mais resultados ajustando o argumento de busca.

• Remover as aspas pode possibilitar buscas mais amplas: (( decrease in decrease observed programming ) OR ( python code data python programming ))~.
