We studied integration contour deformations in the chiral random matrixtheory of Stephanov with the goal of alleviating the finite-density signproblem. We considered simple ans\"atze for the deformed integration contours,and optimized their parameters. We find that optimization of a single parametermanages to considerably improve on the severity of the sign problem. We shownumerical evidence that the improvement achieved is exponential in the degreesof freedom of the system, i.e., the size of the random matrix. We also comparethe optimization method with contour deformations coming from the holomorphicflow equations.
