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