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