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 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.

• If you are trying to use Boolean operators, they must be ALL CAPS: (("modified time solutions algorithms") OR ("modified multiobjective optimization algorithm"))~.
• Removing quotes may allow a broader search: (( modified time solutions algorithms ) or ( modified multiobjective optimization algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified time solutions algorithms") or ("modified multiobjective optimization algorithm"))*.
