Talvez deva tentar algumas variações de ortografia:
reference sampling » reference sample (Expandir a busca), reference samples (Expandir a busca), relevance sampling (Expandir a busca)
sampling program » labeling program (Expandir a busca), smoking program (Expandir a busca), sampling diagram (Expandir a busca)
coder reference » modern reference (Expandir a busca), model reference (Expandir a busca), mode reference (Expandir a busca)
python python » pythons python (Expandir a busca), piton python (Expandir a busca), pitons python (Expandir a busca)
coder coder » coder decoder (Expandir a busca), code code (Expandir a busca), decoder codec (Expandir a busca)
of python » _ python (Expandir a busca), in python (Expandir a busca)

Você pode obter mais resultados ajustando o argumento de busca.

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