Perhaps you should try some spelling variations:
"modified lighting estimation algorithmssss" » "modified lighting estimation algorithms", "modified lighting estimation algorithm", "modified caging estimation algorithmssss"
"modified objective optimisation algorithm" » "modified objective optimization algorithm", "modified multiobjective optimization algorithm", "modified objective optimization algorithms", "modified objective estimation algorithm", "modified objective estimation 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 objective optimisation algorithm") OR ("modified lighting estimation algorithmssss"))~.
• Removing quotes may allow a broader search: (( modified objective optimisation algorithm ) or ( modified lighting estimation algorithmssss ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified objective optimisation algorithm") or ("modified lighting estimation algorithmssss"))*.
