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

Try widening your search to All Fields.

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

• Performing a fuzzy search may retrieve terms with similar spellings: (("modified adam predictive algorithm") or ("modified objective optimisation algorithm"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("modified adam predictive algorithm") OR ("modified objective optimisation algorithm")).
• Removing quotes may allow a broader search: (( modified adam predictive algorithm ) or ( modified objective optimisation algorithm )).
• Adding a wildcard symbol may retrieve word variants: (("modified adam predictive algorithm") or ("modified objective optimisation algorithm"))*.
