Abstract :
Since its publication 10 years ago, the GVF has been used and adapted to various models and problems. Its popularity is certainly due to its effectiveness. The main drawback of GVF and its generalization, is their expensive computation load and its consequence on the capture range. We propose and compare in this work different efficient numerical schemes to solve the GVF and its generalizations.
