Perhaps you should try some spelling variations:
optimization algorithms » optimisation algorithm, estimation algorithms, estimation algorithm
optimized algorithm » optimized algorithms, optimizer algorithms
charging optimized » choosing optimizer
modified charging » modified caging, modified carbon
modified staffing » modified caging

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

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