Hi,
You can use the projectLinear argument in BB::spg to optimize with linear
equality/inequality constraints.
Here is how you implement the constraint that all parameters sum to 1.
require(BB)
spg(par=p0, fn=myFn, project="projectLinear", projectArgs=list(A=matrix(1, 1,
length(p0)), b=1, meq=1))
Hope this is helpful,
Ravi
