Model 1 - Convergence curves, CeSS vs. eSS. The performance of 10 individual, non cooperative threads (in black) is compared with η = 10 cooperative threads that exchange information with τ = 2.53 (in green). The figure shows the logarithm of the objective function value plotted against the computation time. For each method, only the best value found by its 10 threads is shown at every instant.
