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"

Try widening your search to All Fields.

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: (("modified multiobjective optimisation algorithm") or ("modified water solution algorithm"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("modified multiobjective optimisation algorithm") OR ("modified water solution algorithm")).
• Removing quotes may allow a broader search: (( modified multiobjective optimisation algorithm ) or ( modified water solution algorithm )).
• Adding a wildcard symbol may retrieve word variants: (("modified multiobjective optimisation algorithm") or ("modified water solution algorithm"))*.
