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