摘要：A purely numerical method, Direct Computation Method is applied to evaluate Feynman integrals.
This method is based on the combination of an efcient numerical integration and an efcient
extrapolation. In addition, high-precision arithmetic and parallelization technique can be used in
this method if required. We present the recent progress in development of this method and show
results such as one-loop 5-point and two-loop 3-point integrals.
