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

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

• Performing a fuzzy search may retrieve terms with similar spellings: (( modified passive evolution algorithm ) or ( modified allocation optimized algorithms ))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (( modified passive evolution algorithm ) OR ( modified allocation optimized algorithms )).
• Adding a wildcard symbol may retrieve word variants: (( modified passive evolution algorithm ) or ( modified allocation optimized algorithms ))*.
