Talvez deva tentar algumas variações de ortografia:
extractive algorithms » extraction algorithm (Expandir a busca), iterative algorithms (Expandir a busca), subtraction algorithms (Expandir a busca)
python programming » math programming (Expandir a busca)
programming python » programming method (Expandir a busca), programmation python (Expandir a busca), programacao python (Expandir a busca)
algorithms on » algorithms in (Expandir a busca), algorithm on (Expandir a busca), algorithms of (Expandir a busca)
trava marina » travi maria (Expandir a busca), saraiva marina (Expandir a busca), flavia marina (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: "java ((java marine) OR (trava marina)) extractive algorithms on python programming python computer~".
• Adicionar um caractere curinga pode recuperar variações da palavra buscada: java ((java marine) OR (trava marina)) extractive algorithms on python programming python computer*.
