Perhaps you should try some spelling variations:
optimization algorithms » optimisation algorithm, estimation algorithms, estimation algorithm
market optimization » game optimization, parameter optimization, market capitalization
egarch algorithm » search algorithm, source algorithm
modified market » modified male
code » core

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

• If you are trying to use Boolean operators, they must be ALL CAPS: (( code using egarch algorithm ) OR ( modified market optimization algorithms ))~.
• Adding a wildcard symbol may retrieve word variants: (( code using egarch algorithm ) or ( modified market optimization algorithms ))*.
