-To our knowledge, NiaARM is one of only two publicly available software solutions implementing any form of numerical association rule mining, the other one being uARMSolver [@fister_uarmsolver_2020]. The uARMSolver framework, written in C++, also implements the ARM-DE algorithm. Comparatively, NiaARM offers better ease of use, the ability to use of arbitrary nature-inspired algorithms from the NiaPy framework (uARMSolver only implements DE or PSO) and the ability to optimize more interest measures.
