Google Scholar Hu Y, Gansner ER, Kobourov SG (2010) Visualizing graphs and … The main disadvantages of force-directed algorithms include the following: High running time The typical force-directed algorithms are in general considered to run in cubic time (), where is the number of nodes of the input graph. This is because the number of iterations is estimated to be linear (), and in every iteration, all pairs of nodes need to be visited and their mutual repulsive forces computed. This is related to the N-body problem in physics. However, si…
