P-tensor and P_0-tensor are introduced in tensor complementarity problem, which have wide applications in many fields such as game theory, tensor complementarity problem. In this paper, we discuss how to check whether a given symmetric tensor is P(P_0)-tensor or not. For a symmetric tensor, it is a P(P_0)-tensor is equivalent to the positivity(nonnegativity) of a polynomial optimization problem. For such polynomial optimization problem, a SDP relaxation method is proposed. By the proposed method, the P(P_0)-tensor can be detected by solving a finite number of SDP relaxations. Furthermore, numerical examples are reported to show the efficiency of the proposed algorithm.
