Perhaps you should try some spelling variations:
"modified multiobjective optimized algorithms" » "modified multiobjective optimization algorithms", "modified multiobjective optimized algorithm", "modified multiobjective optimizer algorithms"
"modified time solution algorithm" » "modified time evolution algorithm", "modified time convolution algorithms", "modified time evolutionary algorithm", "modified bi1 solution algorithm", "modified male solution algorithm", "modified time solutions algorithm", "modified optimal solution algorithm"

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 time solution algorithm\") OR (\"modified multiobjective optimized algorithms\"))~".
• Removing quotes may allow a broader search: (( modified time solution algorithm ) OR ( modified multiobjective optimized algorithms ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified time solution algorithm") OR ("modified multiobjective optimized algorithms"))*.
