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