When epsilon-expansion of hypergeometric functions is expressible in   terms of multiple polylogarithms: the two-variables examples
  In this talk, we discuss the algorithm for the construction of analytical coefficients of higher order epsilon expansion of some Horn type hypergeometric functions of two variables around rational values of parameters.
