Talvez deva tentar algumas variações de ortografia:
methodology problems » methodology problem (Expandir a busca), methodology process (Expandir a busca), methodological problems (Expandir a busca)
function surface » functional surface (Expandir a busca), functional surfaces (Expandir a busca), function subspace (Expandir a busca)
rotations method » rotation method (Expandir a busca), rotational method (Expandir a busca), rotation methods (Expandir a busca)
coder function » modern function (Expandir a busca), power function (Expandir a busca), over function (Expandir a busca)
method python » method method (Expandir a busca), python python (Expandir a busca)
in rotations » in rotation (Expandir a busca), in rotational (Expandir a busca), and rotations (Expandir a busca)

Você pode obter mais resultados ajustando o argumento de busca.

• As palavras AND, OR e NOT pode ocasionar problemas na busca; tente utilizar as aspas: "(( coder function surface methodology problems ) OR ( in rotations method python programming ))~".
• Adicionar um caractere curinga pode recuperar variações da palavra buscada: (( coder function surface methodology problems ) OR ( in rotations method python programming ))*.
