Talvez deva tentar algumas variações de ortografia:
algorithm optmization » algorithm optimization (Expandir a busca), algorithms optimization (Expandir a busca), algorithmic optimization (Expandir a busca)
optmization problem » optimization problem (Expandir a busca), optimization problems (Expandir a busca), optimisation problems (Expandir a busca)
decrease function » degree function (Expandir a busca), degree functions (Expandir a busca)
reverse function » reverse auction (Expandir a busca), inverse function (Expandir a busca), reverse auctions (Expandir a busca)
saving algorithm » racing algorithms (Expandir a busca), sensing algorithm (Expandir a busca), learning algorithm (Expandir a busca)

Você pode obter mais resultados ajustando o argumento de busca.

• Remover as aspas pode possibilitar buscas mais amplas: ((decrease function) OR (reverse function)) saving algorithm optmization problem*.
