Hi,
Take a look at the multiStart() function in the "BB" package. This allows you
to specify random multiple starting values, which need not satisfy constraints.
Then you need to specify the constraints using the `projectLinear' argument.

Dear All,
I would like to minimise a nonlinear function subject to linear inequality
constraints as part of an R program. I have been using the constrOptim
function. I have tried all of the methods that come with Optim, but nothing
finds the correct solution. If I use the correct solution as
