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