adaptive-server is a bunch of R code that you can run under Rserve to provide a server that can fit models of intertemporal choice adaptively. Each time a human subject makes a choice, the choice is sent to the server, the server fits a Bayesian model of all the subject's choices so far (using either MCMC via Stan or grid approximation, depending on the model), and the server sends back a new question to ask the subject that in some sense maximizes the question's diagnostic value for model-fitting. You could run adaptive-server on the same machine as the client program, but the point of writing it as a server was that I could run it on a machine with lots of CPU and RAM while keeping my web server on a tiny VPS.

I wrote adaptive-server for use with Builder.


To start the server, try the shell command:

R CMD Rserve --RS-conf Rserv.conf

Rserv.conf should be a file containing something like:

encoding utf8
eval db.path = "adaptive-server-jobs.sqlite"
source init-serv.R

The SQLite database should be initialized with the included jobs-schema.sql.
