Comparison of noise $\tilde{K}$ ${{\tilde{\mathfrak{K}}}}$ and $\tilde{c}$ ${{\tilde{\mathfrak{c}}}}$ eigenvalues between theory (without Russian roulette) and simulation with two-part Russian roulette, given for Problem 1. Notice the break in scale in the top plot. Left: flight-based method. Right: collision-based method.
