Perhaps you should try some spelling variations:
"modified multiobjective optimisation algorithm" » "modified multiobjective optimization algorithm", "modified objective optimization algorithm", "modified multiobjective optimization algorithms", "modified multiobjective estimation algorithm", "modified multiobjective estimation algorithms"
"modified water solution algorithm" » "modified water evolution algorithm", "modified water convolution algorithms", "modified water evolutionary algorithm", "modified male solution algorithm", "modified water absorption algorithm"

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 water solution algorithm") OR ("modified multiobjective optimisation algorithm"))~.
• Removing quotes may allow a broader search: (( modified water solution algorithm ) or ( modified multiobjective optimisation algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified water solution algorithm") or ("modified multiobjective optimisation algorithm"))*.
