Talvez deva tentar algumas variações de ortografia:
learning modeling » learning models (Expandir a busca), learning model (Expandir a busca), learning mode (Expandir a busca)
modeling vpython » modeling method (Expandir a busca)
task decrease » mass decrease (Expandir a busca), risk decreases (Expandir a busca), tasks increase (Expandir a busca)
python python » pythons python (Expandir a busca), piton python (Expandir a busca), pitons python (Expandir a busca)
vpython task » python task (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: (( learning modeling vpython task decrease ) OR ( of python python python programming ))~.
