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 objective allocation algorithmssss" » "modified objective location algorithmssss", "modified objective allocation algorithms"

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 lighting optimisation algorithm") OR ("modified objective allocation algorithmssss"))~.
• Removing quotes may allow a broader search: (( modified lighting optimisation algorithm ) or ( modified objective allocation algorithmssss ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified lighting optimisation algorithm") or ("modified objective allocation algorithmssss"))*.
