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