Perhaps you should try some spelling variations:
optimization algorithms » optimisation algorithm, estimation algorithms, estimation algorithm
optimized algorithms » optimized algorithm, optimizer algorithms
sphere optimization » sphere estimation, stage optimization, response optimization
parameter optimized » parameter optimization

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: (( sphere optimization algorithms ) OR ( parameter optimized algorithms ))~.
• Adding a wildcard symbol may retrieve word variants: (( sphere optimization algorithms ) or ( parameter optimized algorithms ))*.
