Talvez deva tentar algumas variações de ortografia:
robot programming » robots programming (Expandir a busca), goal programming (Expandir a busca), cone programming (Expandir a busca)
coder efficiency » codec efficiency (Expandir a busca), codes efficiency (Expandir a busca), cover efficiency (Expandir a busca)
efficiency robot » efficiency root (Expandir a busca), efficient robot (Expandir a busca), efficiency but (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)

Você pode obter mais resultados ajustando o argumento de busca.

• Remover as aspas pode possibilitar buscas mais amplas: (( coder coder efficiency robot programming ) OR ( _ python python python programming ))~.
