Talvez deva tentar algumas variações de ortografia:
computation using » computations using (Expandir a busca), computation in (Expandir a busca), composition using (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)
led program » redd program (Expandir a busca), and program (Expandir a busca), aid program (Expandir a busca)
using led » using leaf (Expandir a busca), using lean (Expandir a busca), using lhc (Expandir a busca)

Você pode obter mais resultados ajustando o argumento de busca.

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