Hassett constructed a class of modular compactifications ofby adding weights to the marked points. This leads to a natural wall and chamber decomposition of the domain of admissible weights, where the moduli space and universal family remain constant inside a chamber, and may change upon crossing a wall. The goal of this paper is to count the number of chambers in this decomposition. We relate these chambers to a class of boolean functions known as linear threshold functions (LTFs), and discover a subclass of LTFs which are in bijection with the chambers. Using this relation, we prove an asymptotic formula for the number of chambers, and compute the exact number of chambers forn⩽ 9. In addition, we provide an algorithm for the enumeration of chambers ofand prove results in computational complexity.
