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