Perhaps you should try some spelling variations:
optimization algorithms » optimisation algorithm, estimation algorithms, estimation algorithm
notion optimization » network optimization, policy optimization, allocation optimization
solution algorithm » evolution algorithm, convolution algorithms, evolutionary algorithm
modified positive » modified passive, modified adaptive
positive solution » positive solutions

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 positive solution algorithm ) OR ( modified notion optimization algorithms ))~.
• Adding a wildcard symbol may retrieve word variants: (( modified positive solution algorithm ) or ( modified notion optimization algorithms ))*.
