By 2023 Reverse Monte Carlo (RMC) modelling, a method for modelling structural disorder in liquids, amorphous and crystalline solids,  has been around for 35 years. The first international meeting dedicated to RMC was organised by Robert McGreevy and was held in Studsvik (Sweden) in 1994. In October 2003, we met in Budapest to hold the 2nd RMC Conference. It was there where the participants agreed to hold such meetings every third year. According to this plan, the 3rd RMC and 4th meetings were held in Hotel Normafa, Budapest (Hungary) late September in 2006 and early October, 2009, respectively. As the attendees would remember, the meeting in 2012 had to be transferred in the last minute to another venue within Budapest, Holiday Beach Wellness Hotel, where also our last two meetings, RMC-6 and RMC-7 were held in 2015 and 2018.


Just before COVID hit us all, it had been possible to conduct an international meeting on RMC in Kumamoto (Japan) in February 2020: it was the '1st Pan-Pacific Reverse Monte Carlo Conference' -- this event is the '(+1)' indicated in the event title.

As three years has passed since the last RMC meeting, and also, the COVID-situation seems to be advantageous these days, we think it's high time to hold the next international conference on (all the diverse aspects of) Reverse Monte Carlo modelling. 

Topics to be covered: anything related to RMC (even remotely). 

  • Structure of liquids and amorphous materials;
  • Interpretation of powder diffraction data for crystals;
  • Software development: new computer codes (RMC, EPSR, PFGui, etc...);
  • Related methods: we plan to hold sessions dedicated to EPSR and PDFGui (other suggestions also welcome);
  • Extending the applications of RMC: modelling small angle scattering, reflectometry, inelastic scattering, EXAFS, NMR, etc...
  • Etc... 


Conference fee

We are sorry to announce that for covering the steeply rising costs (of everything, especially in downtown Budapest...), we have to collect a conference fee this year.

We are still negotiating for better prices. As it looks now, the conference fee will be around 250 EUR (or, as we hope, less). It will cover the rental of the conference room, coffee breaks (and perhaps a simple lunch).



As indicated above, instead of a 'conference hotel', the 2023 event will take place in a proper conference room, in downtown Budapest. 

We kindly ask participants to organise for their own accomodations -- there should be no problem to find one via the usual channels (, etc...).

We are, of course, happy to provide help in finding a place to stay.


Please register a.s.a.p.  -- thank you!

The number of attendees is limited to about 80, due to the capacity of the conference room.

We will try to provide the possibility of delivering an oral presentations with everyone interested. Poster presentations will also be facilitated.
