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