Talvez deva tentar algumas variações de ortografia:
math programming » and programming (Expandir a busca), goal programming (Expandir a busca), _ programming (Expandir a busca)
method sampling » methods sampling (Expandir a busca), method sample (Expandir a busca), method settling (Expandir a busca)
sampling math » sampling data (Expandir a busca), sampling date (Expandir a busca), sampling at (Expandir a busca)
coding pitons » loading pistons (Expandir a busca)
coder method » powder method (Expandir a busca), holder method (Expandir a busca), power method (Expandir a busca)
using coding » using coping (Expandir a busca), using coating (Expandir a busca), using cooking (Expandir a busca)

Você pode obter mais resultados ajustando o argumento de busca.

• Remover as aspas pode possibilitar buscas mais amplas: (( coder method sampling math programming ) OR ( using coding pitons python programming ))~.
