JETNET 3.0 includes a ``test deck'' subroutine called JNTDEC. If you call this subroutine, it will test JETNET 3.0 automatically.
The maximum number of layers in JETNET 3.0 is 11, including the input layer, although it is very difficult to find a situation where more than 4 is needed.
The maximum number of input nodes is 1000. This can be changed by changing the parameter MAXI in the PARAMETER statement in each routine.
The maximum number of output nodes is 1000. This can be changed by changing the parameter MAXO in the PARAMETER statement in each routine.
The maximum total number of nodes is 2000 (not including the input nodes). This can be changed by changing the parameter MAXV in the PARAMETER statement in each routine.
The maximum total number of weights is 150000 . This can be changed by changing the parameter MAXM in the PARAMETER statement in each routine.
The maximum size of the Hessian matrix is 
. This can be
changed by changing the parameter MAXD2E in all relevant PARAMETER
statements.
The code is written entirely in FORTRAN 77. All subroutine and common block names start with the characters JN or JM, except for the functions GAUSJN, GJM, GJN, ERRJN and RJN.
