Perhaps you should try some spelling variations:
multiobjective optimisation » multiobjective optimization, objective optimization
optimization algorithm » optimization algorithms, estimation algorithm, estimation algorithms
optimisation algorithm » optimization algorithms, estimation algorithm, estimation algorithms
game optimization » stage optimization, qoe optimization, market optimization
modified game » modified male, 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 game optimization algorithm ) OR ( modified multiobjective optimisation algorithm ))~".
• Adding a wildcard symbol may retrieve word variants: (( modified game optimization algorithm ) OR ( modified multiobjective optimisation algorithm ))*.
