Talvez deva tentar algumas variações de ortografia:
integer programming » linear programming (Expandir a busca)
decrease integer » decrease catheter (Expandir a busca), decrease after (Expandir a busca), decrease income (Expandir a busca)
python redes » python regius (Expandir a busca), python code (Expandir a busca)
in decrease » in decreased (Expandir a busca), on decrease (Expandir a busca), pain decrease (Expandir a busca)
ptn python » piton python (Expandir a busca), pytm python (Expandir a busca), in python (Expandir a busca)
redes ptn » redes pon (Expandir a busca), redes p2p (Expandir a busca), redes par (Expandir a busca)

Você pode obter mais resultados ajustando o argumento de busca.

• Remover as aspas pode possibilitar buscas mais amplas: (( decrease in decrease integer programming ) OR ( python redes ptn python programming ))~.
