Version 0.4.1

Features:

• Added Solution Quality Estimator for Knapsack, other problems will be supported in the future
• Added two different Grover Algorithms as SAT Solvers
• Added SharpSAT problem mask and two different classical solvers for it
• Added two QUBO solvers that utilize the PlanQK API (Quantagonia and Kipus custom solver)

---

Refactor:

• Introduced Python Virtual Environments for all Python Solvers
• Updated GAMS MaxCut Solver to support new GAMS 49 (ran on GAMS 42 before)
• Fixed Several Issues with Quantum Solvers that occured with new Qiskit version. We are still stuck on Qiskit 1.4.
• Updated CI Scripts and Dockerfile for Virtual Environments and new types of GAMS licenses

Version 0.4.0

Features:

• Implemented Backend Support for Demonstrators

Add QUBO Problem Mask

• Qiskit Solver using QAOA
• Qrisp Solver using QAOA
• D-Wave Annealing Solver

Add Vehicle Routing Problem Mask

• LKH3 Solver
• Qrisp Solver using Grover
• Clusterer (k-means, 2-phase)

Add Traveling Sales Person Problem Mask
