Perhaps you should try some spelling variations:
"modified objective optimization algorithms" » "modified objective optimisation algorithm", "modified objective estimation algorithms", "modified objective estimation algorithm", "modified multiobjective optimization algorithms"
"modified positive solution algorithm" » "modified positive evolution algorithm", "modified positive convolution algorithms", "modified positive evolutionary algorithm", "modified passive solution algorithm", "modified adaptive solution algorithm", "modified positive solutions algorithm"

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 objective optimization algorithms") OR ("modified positive solution algorithm"))~.
• Removing quotes may allow a broader search: (( modified objective optimization algorithms ) or ( modified positive solution algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified objective optimization algorithms") or ("modified positive solution algorithm"))*.
