[R] Why different results with different initial values for MLE (optim)!

Hi, All:

    I used optim() to minimise likelihood function for fitting the data to a partiuclar distribution. The function is converged and the value of log-likelihood is different when I change the intial value.     

    Whether it means the program does not work well?

   Thanks!
