Talvez deva tentar algumas variações de ortografia:
sampling program » labeling program (Expandir a busca), smoking program (Expandir a busca), sampling diagram (Expandir a busca)
based sampling » and sampling (Expandir a busca), blood sampling (Expandir a busca), based sample (Expandir a busca)
python python » pythons python (Expandir a busca), piton python (Expandir a busca), pitons python (Expandir a busca)
coder action » border action (Expandir a busca), under action (Expandir a busca), power action (Expandir a busca)
action based » reaction based (Expandir a busca), function based (Expandir a busca)
in python » _ python (Expandir a busca)

Você pode obter mais resultados ajustando o argumento de busca.

• Remover as aspas pode possibilitar buscas mais amplas: (( coder action based sampling program ) OR ( in python python python programming ))~.
