Perhaps you should try some spelling variations:
"modified lighting optimisation algorithm" » "modified lighting optimization algorithms", "modified lighting estimation algorithm", "modified lighting estimation algorithms", "modified caging optimisation algorithm"
"modified learning method algorithm" » "mobile learning method algorithm", "modified caging method algorithm", "modified learning mom algorithm", "modified learning methods algorithm", "modified graining methods algorithm", "modified learning emotion algorithm"

You may be able to get more results by adjusting your search query.

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