Description
In this talk, I will introduce new tools towards the evaluation of Feynman integrals, including AMFlow and Blade. AMFlow, based on auxiliary mass flow method, which can numerically evaluate Feynman integrals in an efficient and systematic way, have proved to be very useful in the past year. Another tool named Blade, which is based on block-triangular relations among Feynman integrals, can perform much faster samling in finite field than traditional integration-by-parts system and as a result, much more efficient reduction of Feynman integrals.
