Comparison of various combinations of the optimization algorithms for the IBD data set with K = 2 ancestral populations
Experiments were performed on an Intel Xeon 2.8 GHz machine. Runtimes are reported as hours:minutes. The strict convergence criterion ∈ = 10−4 is used except where indicated otherwise. In A, acceleration is carried out by our quasi-Newton method with q = 3 secant conditions. In B, the case q = 0 represents unaccelerated block relaxation.
