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