<code> let middle = min_idx + ((max_idx - min_idx) / 2); </code>

Respect!

Author here: I'm curious if anyone has run into similar observations: founders that sounds great, are talented/ambitious, but their purpose for building is more aligned with internal satisfaction than external reality.

It's pretty interesting, but Bebop is barely treat motivated, and mostly inside. Once you take him outside, especially in open areas, he becomes more interested in tracking movement and chasing things.

I believe it's explained by the job we've asked Greyhounds to do: see movement, get released, run after it. Once you let go, that's it, the dog needs to be motivated enough by the running animal or lure, and there's no chance to reinforce the loop once it starts!

If I repeat this experiment, I'll be a lot more careful about that, or also alternate which direction I'm standing in.

I didn't realize R/L preference was biased until I did the data analysis, and during the trials he was picking from both hands often enough that I perceived it as roughly 50% depending on the treats!

With Bebop, it's dead birds! He also finds them, then checks the same spot for months afterwords!

Author here, yes, that's correct.

The initial set-up was to do 3 comparisons of the 5 treats (30 trials), alternate between right and left hand, then write a quick python script to randomize the order.

A bit more than halfway through the experiment, I ran the model and realized that A/D/E were the only contenders left, so I removed the B/C trials and added more A/D/E trials.

That's awesome! Thank you!

Author here: I did a quick experiment with my Greyhound, Bebop, to figure out the treat he prefers best using pair-wise comparison analyzed with the Bradley-Terry model. Same tech as Elo scores in chess, and several other places! Enjoy!

Hi Folks, author here! Curious if people have run into the same issues, or heard the same things.
