Talvez deva tentar algumas variações de ortografia:
coarse program » course program (Expandir a busca), course programs (Expandir a busca), care program (Expandir a busca)
ranking python » ranking method (Expandir a busca), ranking position (Expandir a busca)
using ranking » using stacking (Expandir a busca), using resting (Expandir a busca)
python python » pythons python (Expandir a busca), piton python (Expandir a busca), pitons python (Expandir a busca)
of coarse » of course (Expandir a busca), of courses (Expandir a busca), _ coarse (Expandir a busca)

Você pode obter mais resultados ajustando o argumento de busca.

• Remover as aspas pode possibilitar buscas mais amplas: (( AND computation of coarse program ) OR ( using ranking python python programming ))*.
