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