Perhaps you should try some spelling variations:
optimization algorithm » optimization algorithms, estimation algorithm, estimation algorithms
optimisation algorithm » optimization algorithms, estimation algorithm, estimation algorithms
optimizer algorithms » optimized algorithms, optimized algorithm, optimization algorithms
game optimization » stage optimization, qoe optimization, market optimization

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

• Performing a fuzzy search may retrieve terms with similar spellings: (( game optimization algorithm ) or ( game ((optimizer algorithms) or (optimisation algorithm)) ))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (( game optimization algorithm ) OR ( game ((optimizer algorithms) OR (optimisation algorithm)) ))*.
