Perhaps you should try some spelling variations:
solutions algorithm » solution algorithm, evolution algorithm, evolutionary algorithm
adaptive solutions » positive solutions
one approximation » time approximation, _ approximation, rough approximations
modified adaptive » modified passive
modified one » modified male, modified near, modified orca

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 one approximation algorithms ) OR ( modified adaptive solutions algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (( modified one approximation algorithms ) or ( modified adaptive solutions algorithm ))*.
