R help - Jul 2007 - How to set constraints on output layer of Neural Networks

Hi,

Please bear with me as I never use NN in R before. I have a network whose my
output has, says K node. I would like to put a set of constraints on this layer.
Indeed, I have two type of constraints. The first type is that their outputs
should sum up to one. The second type is monotonic increasing from the first
output node to the K-th node. How can I achieve this? Thank you so much in
advance.
