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