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