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

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 multiobjective optimization algorithms") OR ("modified a predictive algorithm"))~.
• Removing quotes may allow a broader search: (( modified multiobjective optimization algorithms ) or ( modified a predictive algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified multiobjective optimization algorithms") or ("modified a predictive algorithm"))*.
