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