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 trace evolutionary algorithm" » "modified trace evolution algorithm", "modified trace solution algorithm", "modified traces evolutionary algorithm", "modified male evolutionary algorithm", "modified orca evolutionary 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 multiobjective optimisation algorithm") OR ("modified trace evolutionary algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"modified multiobjective optimisation algorithm\") OR (\"modified trace evolutionary algorithm\"))".
• Removing quotes may allow a broader search: (( modified multiobjective optimisation algorithm ) OR ( modified trace evolutionary algorithm )).
• Adding a wildcard symbol may retrieve word variants: (("modified multiobjective optimisation algorithm") OR ("modified trace evolutionary algorithm"))*.
