Abstract
Water drops in rivers can intelligently find the shortest path to the sea. The Intelligent Water Drops (IWD) algorithm was introduced in 2007 based on this behavior. In this algorithm, water drops have two important features: velocity and the amount of soil they carry, which they collect from the ground. The less soil they have, the faster they can move. The soil amount represents information exchanged between the ground and the water drops; as more drops pass over a piece of ground, its soil amount decreases. A drop prefers a path with less soil. If the movement steps of the drops are considered discrete, it can be assumed that the drop moves on the nodes of a graph. In the algorithm, water drops represent candidate solutions and are randomly initialized at the nodes of the graph
