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 convolution algorithms" » "modified time evolution algorithm", "modified time solution algorithm", "modified time evolution algorithms", "modified bi1 convolution algorithms", "modified male convolution algorithms"

You may be able to get more results by adjusting your search query.

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