标题： Kira 3: integral reduction with efficient seeding and optimized equation selection

摘要： 我们介绍了Kira的版本3，这是一个用于量子场论和引力波物理高精度计算的费曼积分约化程序。 基于之前的版本，Kira 3引入了优化的种子生成和方程选择算法，显著提升了多圈和多尺度问题的性能。 新功能包括方便的数值采样、符号积分约化以及支持用户定义的附加关系。 我们通过两个和三个圈拓扑的基准测试展示了其能力，展示了相比Kira 2.3高达两个数量级的改进。 Kira 3已公开发布，并准备支持粒子物理学及更广泛领域的雄心勃勃的项目。 显示英文摘要

摘要： We present version 3 of Kira, a Feynman integral reduction program for high-precision calculations in quantum field theory and gravitational-wave physics. Building on previous versions, Kira 3 introduces optimized seeding and equation selection algorithms, significantly improving performance for multi-loop and multi-scale problems. New features include convenient numerical sampling, symbolic integration-by-parts reductions, and support for user-defined additional relations. We demonstrate its capabilities through benchmarks on two- and three-loop topologies, showcasing up to two orders of magnitude improvement over Kira 2.3. Kira 3 is publicly available and poised to support ambitious projects in particle physics and beyond.
