Talvez deva tentar algumas variações de ortografia:
functional approximation » function approximation (Expandir a busca), fractional approximations (Expandir a busca), rational approximation (Expandir a busca)
approximation algorithm » approximation algorithms (Expandir a busca), propagation algorithm (Expandir a busca)
electricity and » electrical and (Expandir a busca), electric and (Expandir a busca)
to electricity » the electricity (Expandir a busca), of electricity (Expandir a busca), _ electricity (Expandir a busca)
algorithm to » algorithm _ (Expandir a busca), algorithms _ (Expandir a busca)
routine and » routines and (Expandir a busca), routing and (Expandir a busca), routine care (Expandir a busca)
