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