Perhaps you should try some spelling variations:
"modified staffing optimization algorithm" » "modified staffing optimization algorithms", "modified staffing optimisation algorithm", "modified staffing estimation algorithm", "modified caging optimization algorithm"
"modified parameter optimized algorithms" » "modified parameter optimized algorithm", "modified parameter optimizer algorithms", "modified parameter optimization 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 parameter optimized algorithms") or ("modified staffing optimization algorithm"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("modified parameter optimized algorithms") OR ("modified staffing optimization algorithm")).
• Removing quotes may allow a broader search: (( modified parameter optimized algorithms ) or ( modified staffing optimization algorithm )).
• Adding a wildcard symbol may retrieve word variants: (("modified parameter optimized algorithms") or ("modified staffing optimization algorithm"))*.
