Perhaps you should try some spelling variations:
allocation optimized » allocation optimization
optimized algorithms » optimized algorithm, optimizer algorithms, optimization algorithms
solution algorithm » evolution algorithm, convolution algorithms, evolutionary algorithm
modified positive » modified passive, modified adaptive
positive solution » positive solutions

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: (( modified positive solution algorithm ) OR ( modified allocation optimized algorithms ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( modified positive solution algorithm ) OR ( modified allocation optimized algorithms ))".
• Adding a wildcard symbol may retrieve word variants: (( modified positive solution algorithm ) OR ( modified allocation optimized algorithms ))*.
