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