Perhaps you should try some spelling variations:
"modified multiobjective estimation algorithms" » "modified multiobjective optimization algorithms", "modified multiobjective estimation algorithm", "modified multiobjective optimisation algorithm"
"modified a predictor algorithm" » "modified a predators algorithm", "modified a predation algorithm", "modified _ predictor algorithm", "modified a prediction algorithm", "modified _ prediction algorithm", "modified df predictor algorithm", "modified adam predictor algorithm"

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: (("modified multiobjective estimation algorithms") or ("modified a predictor algorithm"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("modified multiobjective estimation algorithms") OR ("modified a predictor algorithm"))*.
• Removing quotes may allow a broader search: (( modified multiobjective estimation algorithms ) or ( modified a predictor algorithm ))*.
