In this paper, we revisit the main principles for constructing polynomial-time primal-dual interior-point algorithms (IPAs). Starting from the break-through paper by Gonzaga (1989), their development was related to the barrier methods, where the objective function was added to the barrier for...

This article examines certain key features of the White House Executive Order on Artificial Intelligence issued on October 30, 2023. It places this Executive Order in the context of prior US governmental actions related to AI and discusses the legal strength of the Executive Order. The article...

This paper investigates whether there have been time periods between 1999 and 2019 in Hungary when government spending has been self-financing, i.e., when the government has faced a fiscal free lunch. By self-financing, it is meant that government spending, initially financed by issuing bonds,...

In this paper, we introduce a general long-step algorithmic framework for solving linear programming problems based on the algebraically equivalent transformation technique proposed by Darvay. The main characteristics of the proposed general interior point algorithm are based on the long-step...

With the rapid development of the Chinese economy, the proliferation of Chinese companies worldwide, and the increased presence of Chinese business schools in the international academic discourse, the research on Chinese organizations became a major research stream in international journals. A...

A kutatásom során kisebb-nagyobb környezeti változások befolyásolták a disszertáció végleges formáját, illetve kutatási irányát és ezen kutatások eredőjét is. A világunkban tomboló Covid19 pandémia más megvilágításba helyezte az eredeti kutatásomat. Eredetileg az ipari...

While the Earth’s resources and capability are at its limits, while large part of the society is suffering from hardship, the other part is responsible for overconsumption, enormous waste generation. Pollution combined with self-centred human attitude led to the most crucial situation in our...

The Anthropocene is characterized by the dominance of social arrangements prioritizing material growth (related to social power) over other concerns, such as human and non-human well-being, or the ecosystems’ capacity to sustain life. Despite significant potentials to reduce environmental...

Ez a disszertáció két területet egyesít: a Turizmust és a Dizájnt. Az összevezetés domináns fogalmi gerincét az a tanulási folyamat képezi, amely mindkét területen jelen van. Az olyan új desztinációk számára, mint például az Ipolymente, amelyeket még nem hoztak létre, és...
