Perhaps you should try some spelling variations:
optimisation algorithm » optimization algorithms, estimation algorithm, estimation algorithms
optimized algorithm » optimized algorithms, optimizer algorithms
near optimisation » _ optimisation, network optimization
modified adaptive » modified passive
modified near » modified seird, modified adam

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 near optimisation algorithm ) OR ( modified adaptive optimized algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (( modified near optimisation algorithm ) or ( modified adaptive optimized algorithm ))*.
