[R] SQP with Constraints

[Ravi Varadhan]

Look at the solve.QP() function in the "quadprog" package.

Subject: [R] SQP with Constraints

I am trying to optimize  function similar to the following:

Minimize x1^2 - x2^2 - x3^2

st x1 < x2
    x2 < x3

The constraint is that the variables should be monotonically increasing. Is
there any package that implements Sequential Quadratic Programming with
ability include these constraints???

Thanks you.

Ravi
