Perhaps you should try some spelling variations:
"modified multiobjective optimization algorithms" » "modified multiobjective optimisation algorithm", "modified multiobjective estimation algorithms", "modified multiobjective estimation algorithm"
"modified time solutions algorithms" » "modified time solution algorithm", "modified time evolution algorithm", "modified time convolution algorithms", "modified time evolution algorithms", "modified mild solutions algorithms", "modified bi1 solutions algorithms", "modified male solutions algorithms"

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 algorithms") OR ("modified time solutions algorithms"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"modified multiobjective optimization algorithms\") OR (\"modified time solutions algorithms\"))".
• Removing quotes may allow a broader search: (( modified multiobjective optimization algorithms ) OR ( modified time solutions algorithms )).
• Adding a wildcard symbol may retrieve word variants: (("modified multiobjective optimization algorithms") OR ("modified time solutions algorithms"))*.
