Talvez deva tentar algumas variações de ortografia:
convolved problem » unsolved problem (Expandir a busca), solved problem (Expandir a busca), coupled problem (Expandir a busca)
using convolved » using controlled (Expandir a busca), using conserved (Expandir a busca), using controller (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)
coder using » coders using (Expandir a busca), cover using (Expandir a busca), code using (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 coder using convolved problem ) OR ( in python python python programming ))~.
