Perhaps you should try some spelling variations:
estimation algorithms » estimation algorithm, optimization algorithms, optimisation algorithm
allocation optimized » allocation optimization
optimized algorithms » optimized algorithm, optimizer algorithms, optimization algorithms
notion estimation » motion estimation

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 optimized algorithms ) OR ( modified notion estimation algorithms ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( modified allocation optimized algorithms ) OR ( modified notion estimation algorithms ))".
• Adding a wildcard symbol may retrieve word variants: (( modified allocation optimized algorithms ) OR ( modified notion estimation algorithms ))*.
