|
* Move operations (operator overloading etc) outside of expression classNao Pross2024-03-1812-554/+356
| | | | | | The new class WithOps (TODO: better name) wraps around an expression tree and provides operator overloading and convenient methods. This requires a big structural change hence most things are now broken.

|
* Fix bug in PolyPartialDiff and add PolyRingExpr.diff(wrt)Nao Pross2024-03-102-7/+19
| | | | | Forgot to premultiply with old exponent, d_x (x^2) = 2 * x, bug was that d_x (x^2) gives x, which is wrong

|
* Fix bug that breaks PolyRingExpr.shape & cleanupNao Pross2024-03-081-12/+12
| | | | | Leaf classes need to overwrite the shape abstractmethod with property but not algebra
* Make Expr a Merkle binary tree to allow subtree comparisonNao Pross2024-03-081-11/+12
|
* Create directory for examplesNao Pross2024-03-081-0/+43
|
* Update READMENao Pross2024-03-071-1/+1
|
* Fix regression in State.from_indexNao Pross2024-03-071-4/+3
| | | | Likely caused by f69cda1b84482a2c5dd4c6b8fcf16aebb7ac11ba
* Finish incomplete implementation of MatVar.to_reprNao Pross2024-03-071-7/+8
|
* Delete mdpoly.leaves make Var, Param, Const ABCsNao Pross2024-03-076-198/+297
| | | | | | | | The change is motivated by the desire of having easy access to wrappers like Const that have the behaviour of expressions of a certain algebra. After this changes Var, Param and Const are ABC and cannot be instantiated, instead one should use (appropriately) PolyVar, MatVar, etc.
