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