Perhaps you should try some spelling variations:
optimization algorithms » optimisation algorithm, estimation algorithms, estimation algorithm
approximation algorithm » approximation algorithms
game optimization » stage optimization, qoe optimization, market optimization
bi1 approximation » time approximation, _ approximation, one approximation
modified game » modified male, modified adam

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

• Performing a fuzzy search may retrieve terms with similar spellings: (( modified game optimization algorithms ) or ( modified bi1 approximation algorithm ))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (( modified game optimization algorithms ) OR ( modified bi1 approximation algorithm )).
• Adding a wildcard symbol may retrieve word variants: (( modified game optimization algorithms ) or ( modified bi1 approximation algorithm ))*.
