I am trying to build this model from the PRISM case studies https://www.prismmodelchecker.org/casestudies/robot.php, the table in the Model Statistics section of the case study page states that by setting the constant to 2 I should get a model with 20 states, but by doing so I am getting a model with 18 states, I am using prism version 4.9 on arch Linux with java version 21, I apologize if I am getting something obvious wrong.

Hi Filippo,

I get the same as you. I'm not sure what has changed, but it seems like the statistics in the table are outdated.

Best wishes,

Dave
