Useful to plug any DBI engines.
**External libs**
- Symbolic and Solver Engines (merged into one lib)
- Taint Engine
- SMT2-Lib (included bindings)
**Pin core**

I made these 3 tests and wasn't happy with the results
First test:
Code:
var x = (Math.floor(Math.random() * 10) % 2 == 0); // Random true or false
window.x = (x || !x);
After Compiler ( ADVANCE…

The attached script finishes immediately with `unknown` giving no model.
Patterns are used and model based quantifier instantiation is turned off.
Tried suggestions from the following links with no …

Ignoring Sage's `assume` statements is a bug.
```
sage: assume(x>0)
sage: x.is_positive()
False
sage: u = function('u',x); y = x*u; DE = x*diff(y,x) == y + sqrt(x**2 + y**2)
sage: desolve(DE, u)
x =…

Cryptol fails to find a satisfying assignment for any formula containing a shift by a symbolic amount, if an index of width n is used to shift a bitvector of width greater than 2^n. (For example, shi…

In Cryptol, we use `sbvShiftLeft` and `sbvShiftRight` to implement symbolic shifting. If a symbolic index of width n is used to shift a bitvector of width greater than 2^n, then SBV generates SMT-Lib …

When running the debugger via CLI, `p` or `print` followed by an expression will return another expression, just as in the Alloy Analyzer's evaluator.
This feature should be easier than #3 and should…

I'm not completly sure it's opam or aspcud related, but I found a bug in the dependency resolution algorithm.
In a fresh new switch (here, it's an alias of 3.12.1), and with the [opamocsigen](https:/…

I'm by no means an expert in these areas, but the problem which the resolver attacks seems to be a classic CS 'constraint optimisation problem'.
You have a set of variables (gem versions) and constra…
