Contains both re-implementations of some logical and extra-logical operators for a microKanren, as well as experimental results bench-marking those variations on some small programs.
We structure the re-implementations through several files.
These files are tested against Racket 8.7.

In order to build the paper, you should have pygments, xelatex,
biber installed and available on path. You should then be able to
type make, as the default target is the paper.
The examples sub-directory describes some of the work testing examples suggested to see a big performance wrt left associating conjuction. This was a more complicated story than had seemed at first, where rather than uniformly reordering association, instead the improvement was from locally adjusting that search strategy by use of higher-order goals.
With the logo example, we also saw very little improvement from uniformly re-associating conjunctions.
With the quines example, we did see some reasonable improvements over the baseline. However this was using Nada Amin's unification-only quines interpreter, which means deBruijn indices for variables. So this too has some confounding factors. Outstanding work: completely integrate disequality constraints into the microKanren versions, so that at least we do not need deBruijn indices, and then truly isolate the performance impact on quines.
These tests in their current state are:
| File & Purpose |

| Incipient program for quines interp w/o disequality |
| Incipient program for disequality based quines interp |
| Incipient program to reify a constraint store |
