In this work we prove that a related notion called the quasicentral path, introduced by Argaez and Tapia in nonlinear programming, while being a less restrictive notion is suciently strong to guide the iterates towards a solution of the linear program. We use a new merit function for advancing to the quasicentral path, and weighted neighborhoods as proximity measures of this central region. We prove global convergence theory, and present numerical results that demonstrate the eectiveness of the algorithm. Keyphrases: Interior point methods, Newton's method, Primal-Dual Methods, linear programming
