Perhaps you should try some spelling variations:
"modified multiobjective estimation algorithm" » "modified multiobjective optimization algorithm"
"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.

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