Perhaps you should try some spelling variations:
"modified objective optimization algorithms" » "modified objective optimisation algorithm", "modified objective estimation algorithms", "modified objective estimation algorithm", "modified multiobjective optimization algorithms"
"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 objective optimization algorithms") OR ("modified a predictor algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"modified objective optimization algorithms\") OR (\"modified a predictor algorithm\"))".
• Removing quotes may allow a broader search: (( modified objective optimization algorithms ) OR ( modified a predictor algorithm )).
• Adding a wildcard symbol may retrieve word variants: (("modified objective optimization algorithms") OR ("modified a predictor algorithm"))*.
