Perhaps you should try some spelling variations:
"modified lighting optimization algorithmss" » "modified lighting optimization algorithms", "modified lighting optimisation algorithm", "modified lighting estimation algorithms", "modified lighting optimization algorithmsss", "modified lighting optimisation algorithmss", "modified lighting estimation algorithmss", "modified staffing optimization algorithmss", "modified caging optimization algorithmss"
"modified parameters optimization algorithm" » "modified parameter optimization algorithm", "modified parameter estimation algorithm", "modified parameters optimization algorithms", "modified parameters optimisation algorithm", "modified parameters estimation 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 lighting optimization algorithmss") OR ("modified parameters optimization algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"modified lighting optimization algorithmss\") OR (\"modified parameters optimization algorithm\"))".
• Removing quotes may allow a broader search: (( modified lighting optimization algorithmss ) OR ( modified parameters optimization algorithm )).
• Adding a wildcard symbol may retrieve word variants: (("modified lighting optimization algorithmss") OR ("modified parameters optimization algorithm"))*.
