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 objective optimization algorithms" » "modified objective optimisation algorithm", "modified objective estimation algorithms", "modified objective estimation algorithm", "modified multiobjective optimization algorithms"

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

• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"modified objective optimization algorithms\") OR (\"modified lighting optimization algorithmss\"))~".
• Removing quotes may allow a broader search: (( modified objective optimization algorithms ) OR ( modified lighting optimization algorithmss ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified objective optimization algorithms") OR ("modified lighting optimization algorithmss"))*.
