### Restricting Parameter Domains

Posted:

**Tue Jun 17, 2014 6:09 am**Is it possible to restrict the domain of a parameter such that it:

> takes only odd numbers (subset of above case)

I do remember reading that:

> takes only integral values

> takes only odd numbers (subset of above case)

I do remember reading that:

So not sure if it just not allowed or not as efficient if we restrict the parameter space. If allowed, how do we go about achieving it?The PRAXIS optimizer used by NEURON requires a continuous objective function, so restricting parameter space can actually interfere with it
