Perhaps you should try some spelling variations:
"modified multiobjective optimization algorithm" » "modified multiobjective optimization algorithms", "modified multiobjective optimisation algorithm", "modified multiobjective estimation algorithm"
"modified time evolution algorithm" » "modified time solution algorithm", "modified time evolutionary algorithm", "modified time convolution algorithms", "modified bi1 evolution algorithm", "modified male 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 optimization algorithm") OR ("modified time evolution algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"modified multiobjective optimization algorithm\") OR (\"modified time evolution algorithm\"))".
• Removing quotes may allow a broader search: (( modified multiobjective optimization algorithm ) OR ( modified time evolution algorithm )).
• Adding a wildcard symbol may retrieve word variants: (("modified multiobjective optimization algorithm") OR ("modified time evolution algorithm"))*.
