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 algorithms" » "modified water solution algorithm", "modified water evolution algorithm", "modified water convolution algorithms", "modified male solution algorithms", "modified water absorption algorithms"

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

• Performing a fuzzy search may retrieve terms with similar spellings: (("modified water solution algorithms") OR ("modified multiobjective optimisation algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"modified water solution algorithms\") OR (\"modified multiobjective optimisation algorithm\"))".
• Removing quotes may allow a broader search: (( modified water solution algorithms ) OR ( modified multiobjective optimisation algorithm )).
• Adding a wildcard symbol may retrieve word variants: (("modified water solution algorithms") OR ("modified multiobjective optimisation algorithm"))*.
