Multivariable Constrained Optimization

  1. Jun 4, 2010 #1
    i want to find values of a,b,c such that..

    Minimize (a+b+c)
    constrained to

    (x-a)^2 + (y-b)^2 + (z-c)^2 less than equal to R(z)

    (x-a)^2 + (y-b)^2 + (z-c)^2 greater than equal to r(z)

    can anyone help me solving this?? which method should b used for better computation??

    in the above problem," x,y,z" are given and
    one more constraint:

    -z1 < z < z2

    z1,z2 > 0.
