Talvez deva tentar algumas variações de ortografia:
sampling sample » samplings example (Expandir a busca), sampling scale (Expandir a busca), sample sample (Expandir a busca)
sample python » simple python (Expandir a busca), sample paths (Expandir a busca)
rate decrease » rats decreases (Expandir a busca), ratio decrease (Expandir a busca), rate increase (Expandir a busca)
python python » pythons python (Expandir a busca), piton python (Expandir a busca), pitons python (Expandir a busca)
python rate » python data (Expandir a busca), python based (Expandir a busca), python redes (Expandir a busca)

Você pode obter mais resultados ajustando o argumento de busca.

• Remover as aspas pode possibilitar buscas mais amplas: (( sampling sample python rate decrease ) OR ( _ python python python programming ))~.
