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