Perhaps you should try some spelling variations:
optimization algorithm » optimization algorithms, optimisation algorithm, estimation algorithm
error control » export control, order control
va algorithm » _ algorithm, adam algorithm, mom algorithm
control va » control a, control law, control _
parameter » parameters

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

• The words AND, OR and NOT may confuse the search; try adding quotes: "(( error control va algorithm ) OR ( modified parameter optimization algorithm ))~".
• Adding a wildcard symbol may retrieve word variants: (( error control va algorithm ) OR ( modified parameter optimization algorithm ))*.
