Before revision:  To demonstrate the utility of the interpolation scheme , we solve a discrete parameter queuing network optimization problem by embedding the discrete parameters into  continuous space, and then using a continuous space optimization algorithm to find optimal configurations .
After revision:  To demonstrate the utility of the interpolation scheme , we solve a discrete parameter queuing network optimization problem by embedding the discrete parameters into a continuous space. The technique produces smooth interpolations of the objective function, and a continuous space, and then using a continuous space optimization algorithm to find optimal configurations .
