Perhaps you should try some spelling variations:
"modified dorca optimization algorithms" » "modified dorca optimisation algorithm", "modified dorca estimation algorithms", "modified dorca estimation algorithm", "modified dorca optimisation algorithms", "modified dorca estimation algorithmss", "modified policy optimization algorithms", "modified qoe optimization algorithms", "modified orca optimization algorithms"
"modified objective optimization algorithm" » "modified multiobjective optimization algorithm", "modified objective optimisation algorithm", "modified objective estimation algorithm", "modified objective estimation algorithms"

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 objective optimization algorithm") or ("modified dorca optimization algorithms"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("modified objective optimization algorithm") OR ("modified dorca optimization algorithms")).
• Removing quotes may allow a broader search: (( modified objective optimization algorithm ) or ( modified dorca optimization algorithms )).
• Adding a wildcard symbol may retrieve word variants: (("modified objective optimization algorithm") or ("modified dorca optimization algorithms"))*.
