Perhaps you should try some spelling variations:
"modified quantile optimisation algorithm" » "modified quantile optimization algorithms", "modified quantile estimation algorithm", "modified quantile estimation algorithms", "modified adaptive optimisation algorithm"
"modified location optimization algorithm" » "modified location optimization algorithms", "modified location estimation algorithm", "modified location estimation algorithms", "modified allocation optimization algorithm", "modified static optimization algorithm", "modified carbon optimization algorithm"

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