Perhaps you should try some spelling variations:
multiobjective optimisation » multiobjective optimization, objective optimization
optimisation algorithm » optimization algorithms, estimation algorithm, estimation algorithms
pre algorithm » mppt algorithm, qspr algorithm, _ algorithm
learning pre » learning pbel, learning due, learning from

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 multiobjective optimisation algorithm ) OR ( machine learning pre algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (( modified multiobjective optimisation algorithm ) or ( machine learning pre algorithm ))*.
