[R] Creating Optimization Constraints

2012-10-16 Thread boylangc
Good afternoon, In the code below, I have a set of functions (m1,m2,m3,s1,s2, and s3) which represent response surface designs for the mean and variance for three response variables, followed by an objective function that uses the Big M method to minimize variance (that is, push s1, s2, and
