[0, 1] rather than xv ≥ 0, but the point is that an optimal solution of the linear program will never assign any of the variables xv a value strictly greater than 1, because the value of any such variable could always be reduced to 1 without violating any constraints, and this would...

nonlinear least-squares algorithms, and convergence criteria. In general, begin by modifying the coefficient starting values, because nonlinear model fits are particularly sensitive to the starting values for the model coefficients.
