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 stochastic optimization algorithm" » "modified stochastic optimisation algorithm", "modified stochastic estimation algorithm", "modified stochastic estimation algorithms"

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