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