Abstract We classify initial-value problems for extended KdV--Burgers equations via generalized conditional symmetries. These equations can be reduced to Cauchy problems for some systems of first-order ordinary differential equations. The obtained reductions cannot bederived within the framework of the standard Lie approach.
