Automatic implementation of "trivial" constraints in optimization
...rameters: $\alpha, \tau_{fast}, \tau_{slow}, \pi_{fast}$
would be unconstrained.
One could then think of allowing "optim" users to specify more general
boundaries ("lower", "upper") which would be used to generate a parameter
transformation function. This function, say u2c (for "unconstrained to
constrained"), would take a vector of parameters as one of its arguments
and would return another vector (perhaps of a longer length). Then optim
would internaly optimize f(u2c(p)) instead of f. Clearly more sophisticated
constraint specifications (than "lower...
