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