Perhaps you should try some spelling variations:
"modified lighting optimization algorithms" » "modified lighting optimisation algorithm", "modified lighting estimation algorithms", "modified lighting estimation algorithm", "modified lighting optimisation algorithms", "modified lighting estimation algorithmss", "modified staffing optimization algorithms", "modified caging optimization algorithms"
"modified parameter optimization algorithm" » "modified parameter optimisation algorithm", "modified parameter estimation algorithm", "modified parameter estimation algorithms", "modified parameters optimization algorithm"

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

• Performing a fuzzy search may retrieve terms with similar spellings: (("modified parameter optimization algorithm") or ("modified lighting optimization algorithms"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("modified parameter optimization algorithm") OR ("modified lighting optimization algorithms")).
• Removing quotes may allow a broader search: (( modified parameter optimization algorithm ) or ( modified lighting optimization algorithms )).
• Adding a wildcard symbol may retrieve word variants: (("modified parameter optimization algorithm") or ("modified lighting optimization algorithms"))*.
