Hi,
Thanks for the tip!
But I still have problems, which drives me to consider that perhaps I do not use ADFs properly.
After your prescribed modifications, I now receive the following shorter error message :
Initializing Generation 0
ERROR:
The node ADF0[1] in individual pop.subpop.0.species.ind would call its
associated tree, which has an argument terminal with an argument number
(0) >= the ADF/ADM's arity (0). The argument terminal in question
is ARG[0]
ERROR:

I then tried to forget about using ADFarguement , and just declaring
ADF0 in the function set of ADF1, and so on... But , then it gave me a
StackOverflow error...
So I thought, I would have to use not only ADFarguments but also ADFs
as well in the function set of every ADF (like in the lawnmower
example).
In theory, I want to build the following tree :
Master Tree
|
Result Producing Branch
| | |
ADF0 ADF1 ... ADFn
Where ADF0 uses only classic terminals such as Ephemeral Random Constants and input values.
Where ADF1 uses ERCs,input values, and ADF0 as terminals
Where ADF2 uses ERCs,input values, and ADF0 and ADF1 as terminals
...
Where ADFn uses ERCs,input values, and ADF0 to ADFn-1 as terminals
I thought that this can be translated by the following structure in the parameter file for an example of going up to ADF3 :
- First define the result producing branch (I must have 3 ADFs)
gp.fs.0.func.0 = AdfReceptor
gp.fs.0.func.0.nc = nc3
- Second Declare every ADF branch :
gp.fs.0.func.1 = ec.gp.ADF
gp.fs.0.func.1.nc = nc0
gp.fs.0.func.1.tree = 1
gp.fs.0.func.1.name = 0
gp.fs.0.func.2 = ec.gp.ADF
gp.fs.0.func.2.nc = nc0
gp.fs.0.func.2.tree = 2
gp.fs.0.func.2.name = 1
gp.fs.0.func.3 = ec.gp.ADF
gp.fs.0.func.3.nc = nc0
gp.fs.0.func.3.tree = 3
gp.fs.0.func.3.name = 2
Later on, I did the following :
- the function set for ADF0 does just declare ERCs or input terminals.
- The function set for ADF1 does declare : one ADFarguement and ADF0, and the other usual terminals
- The function set for ADF2 does declare : 2 ADFarguements and ADF0 and ADF1, and the other usual terminals
...
- The function set for ADFn does declare : n ADFarguement and from ADF0 to ADFn-1, and the other usual terminals
But it gives me the same type of error messages.
So, I am not sure anymore about how to structure the parameter file to get the ADFs tree described above.
What would be the correct way?

Short version: you're doing gp.fs.1.func.0.arg=1 and gp.fs.1.func.
1.arg=2 when you should be doing gp.fs.1.func.0.arg=0 and gp.fs.
1.func.1.arg=1.
Long version. ADFs are called like any other function; they can have
arguments. For example,
(adf1 4 (sin 3))
Will pass in the 4 and Sin(3) to the ADF1 function. The ADF1
function will then call the ADF1 tree. Inside the ADF1 tree you can
access 4 and Sin(3) respectively using two ADFArgument functions --
let's call them ARG0 and ARG1, like this:
(arg0)
or
(arg1)
Arg0 and Arg1 are just names. To know which argument an arg function
will return, you need to tell it. Specifically, ADFArgument
functions have each will have an 'arg' parameter, for example, gp.fs.
1.func.0.arg, which says which argument number that ADFArgument
represents. Argument numbers start at 0, so the '4' argument is
number 0 and the 'Sin(3)' argument is 1. You're starting at in each
of your trees rather than 0.
