Abstract
In this paper, we propose a generalized viscosity extragradient algorithm in such a way that it does not require prior knowledge of the Lipschitz constants and prove that the generated sequences converges strongly to a common solution of a pseudomonotone equilibrium problem and fixed point problem for a finite family of demicontractive operators in a real Hilbert space. Further, we apply our results to solve various nonlinear analysis problems. Our results generalize and improve results in many different directions. We present numerical results to demonstrate the numerical behaviour of proposed method and to compare it with other methods.
