Perhaps you should try some spelling variations:
optimization algorithmss » optimization algorithms, optimisation algorithm, estimation algorithm
estimation algorithms » estimation algorithm, optimization algorithms, optimisation algorithm
policy optimization » topology optimization
market estimation » market optimization, parameter estimation

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

• Performing a fuzzy search may retrieve terms with similar spellings: (( market estimation algorithms ) or ( policy optimization algorithmss ))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (( market estimation algorithms ) OR ( policy optimization algorithmss ))*.
