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