Publisher's version: http://prola.aps.org/abstract/PRD/v57/i12/p7460_1The critical exponents and the critical amplitude ratio of the scalar model are determined using finite-temperature field theory with an auxiliary mass. A new numerical method is developed to solve an evolution equation. The results are discussed in comparison with values obtained from the other methods
