[1] This is my model, which is not smooth because it contains symbolic functions, absolute values, and if-else statements. I rewrote him into the following ampl code, where beta is the smoothing argument of the symbolic function, Z[2,j,k] is the speed v, and delta is the smoothing parameter of the…

var z1{j in Sfe, k in Scp} = sqrt(Z[2,j,k]^2+seta)-delta; var z3{j in Sfe, k in Scp} = SaP[j,k]-ka Z[1,j,k]-Finit; var s1{j in Sfe, k in Scp} = 0.5*(z1[j,k]/sqrt(z1[j,k]^2+4beta^2)+1); var f1{j in Sfe, k in Scp} = -((Sa P[j,k]-kaZ[1,j,k]-Finit-delta)/((Sa P[j,k]-kaZ[1,j,k]-Finit-delta)^2+4 beta^2…
