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