Talvez deva tentar algumas variações de ortografia:
convex programming » cone programming (Expandir a busca), computer programming (Expandir a busca)
retention convex » retention curve (Expandir a busca), retention curves (Expandir a busca), retention index (Expandir a busca)
coder retention » copper retention (Expandir a busca), color retention (Expandir a busca), water retention (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)
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 retention convex programming ) OR ( in python python python programming ))~.
