Sorry to chime in so late in this discussion, but I've had a busy week. Hopefully I can still shed a little light on the Input stack.<br><br>I decided to implement the Input stack and a handful of Input stack instructions in Psh to make inputs easier to access in a formal manner. The Input stack instructions can be found at this page near the bottom of the README: <a href="http://github.com/jonklein/Psh">http://github.com/jonklein/Psh</a> . I've found the input instructions to be helpful in a variety of situations, especially when there is more than one input for the problem. Let me know if you need any more help here!<br>

I fixed some bug in the evolution code and today it found approximative (0.1 rmsre) solutions with both x^2 and x after 300 generations. Previously I only found x^2.<br>
<br>
(((((0.150111978908561) 0.528050625819725 Integer.* Float.*)) Float.+ Float.Swap (Float.Rot Integer.- Integer.Max (((((Float.< Integer.Min Float.Dup (((Float.Rot) (1.0142690849058 Float./ Integer.+ Integer.+ Integer.-) Integer.Max Float.*))) 1.94731824936981 Float.+)) 1.64833089095734 Float.+)) Float./) Float.=) Float.+ Integer.% (Float.+ 1.52025841305038 1.94731824936981 Float.Min Float.*) Integer.Swap)<br>
<br>
(50 points) which can be simplified to<br>
<br>
(0.150111978908561 0.528050625819725 Float.* Float.+ Float.Dup 1.0142690849058 Float./ Float.* 1.94731824936981 Float.+ 1.64833089095734 Float.+ 1.52025841305038 1.94731824936981 Float.Min Float.*)<br>
<br>
(17 points)<br>
<br>
This is without "inputs instructions" (I didn't implement any kind of them) and with ephemeral random floats limited to [0.0, 2.0]. No simplification is used during the evolution yet. Env, Name, Boolean, Exec and Code are "disabled".<br>
