Perhaps you should try some spelling variations:
optimization algorithm » optimization algorithms, optimisation algorithm, estimation algorithm
convolution algorithms » evolution algorithm, solution algorithm
game optimization » stage optimization, qoe optimization, market optimization
modified passive » modified adaptive
modified game » modified male, modified adam

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

• If you are trying to use Boolean operators, they must be ALL CAPS: (( modified passive convolution algorithms ) OR ( modified game optimization algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (( modified passive convolution algorithms ) or ( modified game optimization algorithm ))*.
