There are a few simplifications of LambertW that have been added:
exp(LambertW(x)) -> x/LambertW(x)
log(LambertW(x)) -> log(x) - LambertW(x)
Lambert(-pi/2) -> I*pi/2
```
Original issue for #5080…

Hi, thanks again for open sourcing your repository. Could you provide a simple example on how to apply your model for discovery of ODE systems (e.g. 2 variables). I had a look at the [lorenz.py](https…

The following code shows that adding to a linear_expression modifies it. This is highly problematic, if the linear expression is reused several times in the code.
```import highspy
h = highspy.Hig…

This is a story that already exists is pivotal tracker.
Solidity should support sum datatype similar to how they are supported by rust.

The following is to collect cases where an integral currently cannot be solved, but it can be solved after simplification is performed. The goal is to keep it condensed and efficient, so ideally we sh…

This issue is to discuss speeding Matrix.inv for matrices with different kinds of expressions. Here is an example of why we might want to do that:
```python
In [12]: M = randMatrix(5) + randMatrix(5…

I am definite integrating a simple expression like:
```python
from sympy import integrate,cos,sqrt,Symbol
x=Symbol('x')
integrate((x**3*cos(x/2)+1/2)*sqrt(4-x**2),(x,-2,2))
```
but I can't get…

I expected to get the same results for calculations in `QQ()` as `QQ` but in this example I do not:

We currently expose the implementation of the `Graph` datatype:
```haskell
data Graph a = Empty
| Vertex a
| Overlay (Graph a) (Graph a)
| Connect (Graph …
