Perhaps you should try some spelling variations:
"modified multiobjective optimized algorithm" » "modified multiobjective optimization algorithm", "modified multiobjective optimized algorithms", "modified multiobjective optimizer algorithms"
"modified sales convolution algorithms" » "modified sales evolution algorithm", "modified sales solution algorithm", "modified sales evolution algorithms", "modified male convolution algorithms", "modified traces 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 optimized algorithm\") OR (\"modified sales convolution algorithms\"))~".
• Removing quotes may allow a broader search: (( modified multiobjective optimized algorithm ) OR ( modified sales convolution algorithms ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified multiobjective optimized algorithm") OR ("modified sales convolution algorithms"))*.
