摘要：
We work on the reconstruction scenario of pilgrim dark energy (PDE) in f(T,T (G) ). In PDE model it is assumed that a repulsive force that is accelerating the Universe is phantom type with (w (DE) <-1) and it is so strong that prevents formation of the black hole. We construct the f(T,T (G) ) models and correspondingly evaluate equation of state parameter for various choices of scale factor. Also, we assume polynomial form of f(T,T (G) ) in terms of cosmic time and reconstruct H and w (DE) in this manner. Through discussion, it is concluded that PDE shows aggressive phantom-like behavior for s=-2 in f(T,T (G) ) gravity.
