X HARMONIC 2026
The tenth conference on Fuzzy Formal Tools for Non Canonical Reasoning (X HARMONIC 2026) will be held in Almadén, Ciudad Real, Spain from October 30th to November 2nd, 2026. The aim of this conference is to create a cooperative environment for the exchange of knowledge and ideas related to the formal concept analysis, fuzzy logic, mathematical morphology, etc.
CONFERENCE VENUE
Almadén is an historic Spanish town internationally recognized as a UNESCO World Heritage Site due to its mercury mines, the largest and oldest operating in the world for over two millennia. This deep industrial past is the focus of the Mining Park, where visitors can descend into the ancient galleries and explore sites like the Royal Prison and the Royal Mining Hospital of San Rafael. Beyond this heritage, the town reflects its status as a regional center through its traditional Manchegan architecture and local cuisine. The successful conversion of the mines after their closure in 2003 has transformed Almadén into a unique cultural tourism destination that balances industrial history with regional charm.
The event will be held at Hotel Casa Betancourt, located in Almadén, Ciudad Real.
