Perhaps you should try some spelling variations:
estimates algorithms » estimation algorithms, estimation algorithm, optimizer algorithms
optimized algorithms » optimized algorithm, optimizer algorithms, optimization algorithms
parameter estimates » parameter estimation
modified lighting » 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 parameter estimates algorithms ) or ( modified lighting optimized algorithms ))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (( modified parameter estimates algorithms ) OR ( modified lighting optimized algorithms )).
• Adding a wildcard symbol may retrieve word variants: (( modified parameter estimates algorithms ) or ( modified lighting optimized algorithms ))*.
