While the algorithms are executing, they will display the Abort Algorithm dialog window. The algorithms check at certain points during their execution if you have pressed the Abort button and, if so, will terminate at that time.
Note that for computationally intensive algorithms, there may be a significant delay between the moment you press the Abort button and the moment the algorithm checks for the button press. This is especially true for computers with single or slow processors.
Since the algorithm did not run to completion, the reported scores for the graph and layout may be incorrect. It is strongly recommended that you execute immediately the Evaluate command from the Algorithms menu if you plan to use the graph or layout shown to ensure that the correct adjacency score and distance scores are computed for this graph and layout.
