Talvez deva tentar algumas variações de ortografia:
lineal programming » linear programming (Expandir a busca), linear programmin (Expandir a busca), line programming (Expandir a busca)
decrease lineal » decreased mineral (Expandir a busca), decrease fungal (Expandir a busca), decrease renal (Expandir a busca)
decrease on » decrease in (Expandir a busca), decrease of (Expandir a busca), decrease and (Expandir a busca)
on decrease » on decreased (Expandir a busca), of decrease (Expandir a busca), or decrease (Expandir a busca)
pitons » citons (Expandir a busca), pitoni (Expandir a busca), pitoes (Expandir a busca)

Você pode obter mais resultados ajustando o argumento de busca.

• Remover as aspas pode possibilitar buscas mais amplas: (( decrease on decrease lineal programming ) OR ( python data pitons python programming ))~.
