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