Perhaps you should try some spelling variations:
"modified multiobjective optimization algorithm" » "modified multiobjective optimization algorithms", "modified multiobjective optimisation algorithm", "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.

• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"modified a predictive algorithm\") OR (\"modified multiobjective optimization algorithm\"))~".
• Removing quotes may allow a broader search: (( modified a predictive algorithm ) OR ( modified multiobjective optimization algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified a predictive algorithm") OR ("modified multiobjective optimization algorithm"))*.
