Perhaps you should try some spelling variations:
"modified multiobjective optimization algorithm" » "modified multiobjective optimization algorithms", "modified multiobjective optimisation algorithm", "modified multiobjective estimation algorithm"
"modified carbon evolution algorithm" » "modified carbon solution algorithm", "modified carbon evolutionary algorithm", "modified carbon convolution algorithms", "modified co evolution algorithm", "modified early 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 carbon evolution algorithm") OR ("modified multiobjective optimization algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"modified carbon evolution algorithm\") OR (\"modified multiobjective optimization algorithm\"))".
• Removing quotes may allow a broader search: (( modified carbon evolution algorithm ) OR ( modified multiobjective optimization algorithm )).
• Adding a wildcard symbol may retrieve word variants: (("modified carbon evolution algorithm") OR ("modified multiobjective optimization algorithm"))*.
