Аннотация
Упрощение рациональных функций является основным процессом, ограничивающим производительность редукции интегралов Фейнмана методом интегрирования по частям (IBP). В настоящей работе применяется подход, связанный с факторизацией знаменателей, возникающих в коэффициентах IBP-редукции, и предлагается алгоритм для эффективного использования факторизованной структуры в интерфейсе FUEL. Разработанный подход позволяет снизить вычислительные затраты и увеличить производительность.
