Perhaps you should try some spelling variations:
multiobjective optimized » multiobjective optimization
optimisation algorithm » optimization algorithms, estimation algorithm, estimation algorithms
optimized algorithm » optimized algorithms, optimizer algorithms
a optimisation » _ optimisation, _ optimization, game optimization
modified a » modified _, modified df, modified adam

You may be able to get more results by adjusting your search query.

• The words AND, OR and NOT may confuse the search; try adding quotes: "(( modified a optimisation algorithm ) OR ( modified multiobjective optimized algorithm ))~".
• Adding a wildcard symbol may retrieve word variants: (( modified a optimisation algorithm ) OR ( modified multiobjective optimized algorithm ))*.
