To support participants from lower-income countries, the workshop fee is discounted by 15% and 30% for those from middle-income and low-income countries, respectively. To determine whether a country is eligible for these discounts, we use the GDP (PPP) per capita as provided by the International Monetary Fund. The current list is based on figures from 2025 and available on Wikipedia. We consider the first 30 countries as high-income, the next 30 as mid-income, and any other country as low-income.
