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

Try widening your search to All Fields.

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

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