Abstract
The notion of the central path plays an important role in the development of most primal-dual interior-point algorithms. In this work we prove that a related notion called the quasicentral path, introduced by Argáez in nonlinear programming, while being a less restrictive notion it is sufficiently strong to guide the iterates towards a solution to the problem. We use a new merit function for advancing to the quasicentral path, and weighted neighborhoods as proximity measures of this central region. We present some numerical results that demonstrate the effectiveness of the algorithm.

Argaez and Tapia chose the name of quasicentral path due to the fact that one of the conditions of the central path is omitted. The authors are fully aware of the fact that they use the term “quasicentral path” to denote mathematically would be known as a variety. However, we choose to retain the already established terminology originally introduced by Argaez and Tapia [1, 2].
