Integrated algorithms for the network control problem
### 1. Introduction Based on the open-source platform Cytoscape, a convenient app called CytoCtrlAnalyser for network controllability analysis has been designed and achieved.This app supports nine algorithms in network controllability: Firstly, five algorithms are implemented to identify the nodes which should be controlled by input control signals to achieve different control objectives: 1. the minimum driver node set (MDS) [1], 2. the minimum steering node set (MSS) [2], 3. the MSS with preference [3, 4], 4. the steering nodes for output control [5] 5. the steering node for state transition [6]. Secondly, four algorithms are implemented to calculate nodes importance in controlling the network in different aspects: 1. control capacity [7], 2. control centrality [8], 3. node classification [9]: indispensable, neutral and dispensable, 4. the probability of a node in a randomly chosen MSS [4]. More details of algorithms, user guide and application examples can be obtained in Supplementary information of corresponding application note at: [] ### 2. Quick Start Following is a short quick start for the usage of CytoCtrlAnalyser, detailed information of the algorithms implemented in this app will be introduced in related papers. 1. Download and install Cytoscape3.0 []. 2. Download the Jar version of CytoCtrlAnalyser. 3. Start Cytoscape, install the CytoCtrlAnalyser.jar through App Manager(Apps → App Manager → Install from file..). 4. Import or open a network. 5. Click **Apps** → **CytoCtrlAnalyser**→ **Start**. 6. It will switch to CytoCtrlAnalyser tab on left panel, choose one or multiple algorithms as you want. 7. Click **Analysis** button. 8. After analysis is done, results will be shown on the table panel. The nodes should be controlled are marked by check symbols in the table. For the node classification: 0, 1 and 2 correspond to dispensable, neutral and indispensable, respectively. ### 3.
