Dear ALPS developers and users

I'm using CT-HYB  impurity solver for single site DMFT problem. While i was simulating single site single-orbital dmft problem using CT-HYB  the value of  total acceptance rate  negative. Is this negative value of total acceptance rate possibly  accepted ?

what is this negative value of total acceptance rate mean ?
