This conference will take place at Visegrád, a nice small city located at north to Budapest with a beautiful surroundings. The conference continues the tradition of the earlier two editions held in Ilieni, Covasna, Romania. Our desire is to provide an opportunity for the presentation and discussion of recent results in applied mathematics and computer science. The scientific program is planned to include 20 minute talks. As at the previous editions the papers will be sent for review and publication in PUMA.
