• Chapter2: Correlation Clustering Resolution Methods
• data&results/Dataset 2.1: This dataset is used to assess the peformances of the exact methods. We generate these complete and incomplete networks through our random signed network generator, which is publicly available online (https://github.com/CompNet/SignedBenchmark). For complete unweighted signed networks, this model relies on only three parameters: n (number of vertices), \ell_0 (initial number of modules) and q_{m} (proportion of misplaced edges, i.e. edges meant to be frustrated by construction). Moreover, we make the assumption that the proportion of misplaced edges is the same inside and between the modules. When it comes to incomplete unweighted signed networks, we introduce two more parameters, which are the density d of the graph and the proportion q_{neg} of the negative edges. The last parameter q_{neg} allows to control the ratio of positive to negative edges.
• comparison between BD(F*_e) and B&C(F_e): containing the network and result files regarding the comparison of two exact methods relying on the ILP formulation with edge variables.
• Comparison between B&C(F_v) and B&C(F_e): containing the network and result files regarding the comparison of two exact methods relying on two ILP formulations: vertex pair vs. edge variables.
• data&results/Dataset 2.2: This dataset is used to assess the peformances of the heuristic methods. We generate these complete and incomplete networks through the same random signed network generator as in Dataset 2.1.
• networks: For complete unweighted signed networks with d = 1, we generate 20 replications for parameter values \ell_0 = 3, n = 50 and q_m = {0.1, 0.2, 0.3, 0.4, 0.5, 0.6}. In these networks, the value of q_{neg} with the considered parameters is approximately 0.7. For incomplete unweighted signed networks with d = {0.25, 0.50}, we generate 20 replications for parameter values \ell_0 = 3, n = 50, q_{m} = {0.1, 0.2, 0.3, 0.4, 0.5, 0.6} and q_{neg} = {0.3, 0.5, 0.7}. In total, we produce 180 and 720 instances for complete and incomplete networks, respectively, which makes a total of 900 instances.
• partitions: containing optimal partitions found by B&C(F_v) and the partitions found by the considered 10 heuristics.
• evaluate-partitions: containing the evaluation results for each heuristic method (e.g. imbalance)
• data&results/Dataset 2.3: This dataset is used to assess the peformances of the heuristic methods. We generate these complete and incomplete networks through our another random signed network generator, which is publicly available online (https://github.com/arinik9/SignedStabilityBenchmark). The optimal solution for a generated network is known by construction. For a given n, d and \ell_0, we first create a perfectly structurally balanced signed network with a built-in module structure. The underlying module structure constitutes the optimal partition. Then, for taking into account different positive to negative ratio values for internal and external edges we generate several signed networks by perturbing the initial signed network without affecting its underlying optimal partition, thanks to its definition of stability range.
• networks: We generate signed networks with parameter values n = 150, d \in {0.25, 1.00} and \ell_0 = {6, 8, 10}. In total, we produce 13 and 49 instances for complete and incomplete networks, respectively, which makes a total of 62 instances.

For complete unweighted signed networks with d = 1, we generate 20 replications for parameter values \ell_0 = 3, n \in {32, 36, 40, 45, 50} and q_m = {0.1, 0.2, 0.3, 0.4, 0.5, 0.6}. In these networks, the value of q_{neg} with the considered parameters is approximately 0.7. For incomplete unweighted signed networks with d = {0.25, 0.50}, we generate 20 replications for parameter values \ell_0 = 3, n \in {32, 36, 40}, q_{m} = {0.1, 0.2, 0.3, 0.4, 0.5, 0.6} and q_{neg} = {0.3, 0.5, 0.7}. In total, we produce 600 and 1,080 instances for complete and incomplete networks, respectively, which makes a total of 1,680 instances.
• partitions: folder containing the partitioning results of two methods: EnumCC(3) vs. OneTreeCC(). Note that the results of OneTreeCC() are not shown for space considerations, except for n=50.
• results/delay_exec_time: all the results and plots regarding the difference of execution times between EnumCC(3) and OneTreeCC() (i.e., EnumCC(3) minus OneTreeCC()), represented on the log-scaled y-axis of the plots. When such difference takes a negative value, this means our proposed method EnumCC(3) runs faster than OneTreeCC().
