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