Talvez deva tentar algumas variações de ortografia:
computations using » computation using (Expandir a busca), populations using (Expandir a busca), computations in (Expandir a busca)
ranking python » ranking method (Expandir a busca), ranking position (Expandir a busca)
mouse program » house program (Expandir a busca), course program (Expandir a busca), lease program (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)
using mouse » during mouse (Expandir a busca), using monte (Expandir a busca), using mode (Expandir a busca)

Você pode obter mais resultados ajustando o argumento de busca.

• Remover as aspas pode possibilitar buscas mais amplas: (( AND computations using mouse program ) OR ( using ranking python python programming ))~.
