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

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