Talvez deva tentar algumas variações de ortografia:
sampling python » sampling method (Expandir a busca), sampling position (Expandir a busca), sampling methods (Expandir a busca)
python sampling » method sampling (Expandir a busca), thin sampling (Expandir a busca), methods sampling (Expandir a busca)
decrease based » decreased base (Expandir a busca), decrease blood (Expandir a busca)
python python » pythons python (Expandir a busca), piton python (Expandir a busca), pitons python (Expandir a busca)
app decrease » spp decrease (Expandir a busca), and decrease (Expandir a busca), any decrease (Expandir a busca)
code app » code and (Expandir a busca), code an (Expandir a busca), code art (Expandir a busca)

Você pode obter mais resultados ajustando o argumento de busca.

• Remover as aspas pode possibilitar buscas mais amplas: (( code app decrease based program ) OR ( python sampling python python programming ))~.
