Talvez deva tentar algumas variações de ortografia:
integer programming » linear programming (Expandir a busca)
decrease processes » disease processes (Expandir a busca), defense processes (Expandir a busca), decay processes (Expandir a busca)
decrease decrease » decrease release (Expandir a busca), disease decreases (Expandir a busca), decrease sucrose (Expandir a busca)
roads decrease » foods decreases (Expandir a busca), goods decreases (Expandir a busca), rate decrease (Expandir a busca)
python based » action based (Expandir a busca)
code integer » some integer (Expandir a busca), models integer (Expandir a busca), pode integrar (Expandir a busca)
code roads » side roads (Expandir a busca), cost roads (Expandir a busca), closed roads (Expandir a busca)
based code » based cost (Expandir a busca), based course (Expandir a busca)

Você pode obter mais resultados ajustando o argumento de busca.

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