Talvez deva tentar algumas variações de ortografia:
decrease computer » decreased compared (Expandir a busca), database computer (Expandir a busca), case computer (Expandir a busca)
python mapping » photon mapping (Expandir a busca), position mapping (Expandir a busca)
mapping tool » mapping to (Expandir a busca), mapping the (Expandir a busca)
decrease at » decrease akt (Expandir a busca), decrease and (Expandir a busca), decrease in (Expandir a busca)
at decrease » rate decrease (Expandir a busca), that decrease (Expandir a busca), and decrease (Expandir a busca)

Você pode obter mais resultados ajustando o argumento de busca.

• Remover as aspas pode possibilitar buscas mais amplas: (( decrease at decrease computer program ) OR ( python mapping tool python programming ))~.
