I see that the basic robot signals Count rather than Attitude. I submit that for the vast majority of robot users, Attitude would be more helpful. At least with an Attitude signal you can perhaps nudge the robot in the right direction - I have no great faith that it ends up doing anything useful with a Count signal.

Attitude would certainly be nice. But that requires the robot to be able to figure out what its attitude is, and it doesn't know how to do that. Attitude signals are an option in the program, but it only enables signalling on the opening lead, and only certain easy situations. Here's what it does when turned on:

signal high with ace or king, low with no Q,
hi with Q over dummy's A or K, or Q over declarer with with no A or K
in dummy, either no trumps in dummy or > 1 card in dummy

If Attitude signals are turned on, does the program understand the notion of an encouraging or discouraging card from its partner?

Yes, but only in the same situations where it knows how to make its own attitude signal. Basically, the way it works is that when it's dealing hands for simulations, it compares what partner led with what it would have led with the same hand -- if it would have led a different card, it considers the hand less likely.
