Perhaps you should try some spelling variations:
"modified multiobjective optimized algorithms" » "modified multiobjective optimization algorithms", "modified multiobjective optimized algorithm", "modified multiobjective optimizer algorithms"
"mapping lighting estimation algorithm" » "mapping learning 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: (("mapping lighting estimation algorithm") OR ("modified multiobjective optimized algorithms"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"mapping lighting estimation algorithm\") OR (\"modified multiobjective optimized algorithms\"))".
• Removing quotes may allow a broader search: (( mapping lighting estimation algorithm ) OR ( modified multiobjective optimized algorithms )).
• Adding a wildcard symbol may retrieve word variants: (("mapping lighting estimation algorithm") OR ("modified multiobjective optimized algorithms"))*.
