BibTeX does not have the right entry for preprints. This is a hack for producing the correct reference:
@Booklet{EasyChair:12070,
author = {Rosemary Adejoh and Andreas Jakoby and Sneha Mohanty and Christian Schindelhauer},
title = {Complexity Bounds for Ray Tracing and Illumination in 2D Using Spy Mirrors},
howpublished = {EasyChair Preprint no. 12070},
year = {EasyChair, 2024}}
