Perhaps you should try some spelling variations:
multiobjective optimisation » multiobjective optimization, objective optimization
optimisation algorithm » optimization algorithms, estimation algorithm, estimation algorithms
method algorithm » mom algorithm
coarse graining » coarse grain, coarse grained
graining method » graining methods, learning method, learning methods

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 ( coarse graining method algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (( modified multiobjective optimisation algorithm ) or ( coarse graining method algorithm ))*.
