Talvez deva tentar algumas variações de ortografia:
line programming » linear programming (Expandir a busca), cone programming (Expandir a busca), linear programmin (Expandir a busca)
prison national » union national (Expandir a busca), prix national (Expandir a busca), prison educational (Expandir a busca)
national line » national life (Expandir a busca), national wine (Expandir a busca), national swine (Expandir a busca)
coding python » codigo python (Expandir a busca), codigos python (Expandir a busca), using python (Expandir a busca)

Você pode obter mais resultados ajustando o argumento de busca.

• Remover as aspas pode possibilitar buscas mais amplas: (( coder prison national line programming ) OR ( using coding python python programming ))~.
