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