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