Perhaps you should try some spelling variations:
"modified multiobjective estimation algorithms" » "modified multiobjective optimization algorithms", "modified multiobjective estimation algorithm", "modified multiobjective optimisation algorithm"
"modified pulse optimized algorithms" » "modified pulse optimized algorithm", "modified pulse optimizer algorithms", "modified pulse optimization algorithms", "modified male optimized algorithms", "modified passive optimized algorithms"

You may be able to get more results by adjusting your search query.

• If you are trying to use Boolean operators, they must be ALL CAPS: (("modified pulse optimized algorithms") OR ("modified multiobjective estimation algorithms"))~.
• Removing quotes may allow a broader search: (( modified pulse optimized algorithms ) or ( modified multiobjective estimation algorithms ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified pulse optimized algorithms") or ("modified multiobjective estimation algorithms"))*.
