Perhaps you should try some spelling variations:
optimization algorithms » optimisation algorithm, estimation algorithms, estimation algorithm
seird optimization » stage optimization, network optimization
egarch algorithm » search algorithm, source algorithm
modified seird » modified near
code » core

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

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