Talvez deva tentar algumas variações de ortografia:
boosting python » boosting method (Expandir a busca)
tree complaint » the complaint (Expandir a busca), tree component (Expandir a busca), the complaints (Expandir a busca)
counts program » points program (Expandir a busca), contents program (Expandir a busca), country programs (Expandir a busca)
using boosting » using rotating (Expandir a busca), using boosted (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)
coder tree » modern tree (Expandir a busca), under tree (Expandir a busca), poder tres (Expandir a busca)

Você pode obter mais resultados ajustando o argumento de busca.

• Remover as aspas pode possibilitar buscas mais amplas: (( coder tree complaint counts program ) OR ( using boosting python python programming ))~.
