Talvez deva tentar algumas variações de ortografia:
efficient algorithms » efficient algorithm (Expandir a busca)
theory efficient » theory coefficients (Expandir a busca), the efficient (Expandir a busca), memory efficient (Expandir a busca)
algorithms array » algoritmos array (Expandir a busca), algorithms are (Expandir a busca), algorithms dream (Expandir a busca)
python python » pythons python (Expandir a busca), piton python (Expandir a busca), pitons python (Expandir a busca)
coder theory » code theory (Expandir a busca), codes theory (Expandir a busca), modern theory (Expandir a busca)
via python » in python (Expandir a busca)

Você pode obter mais resultados ajustando o argumento de busca.

• Remover as aspas pode possibilitar buscas mais amplas: (( coder theory efficient algorithms array ) OR ( via python python python programming ))~.
