GRAPH THEORY APPLIATIONS ON AGRO-ECOSYSTEM

An Agro-ecosystem is always directed by the population interactions living in it and also depends on many aboitic factors. There will be a direct or indirect influence of the elements of the ecosystem. Graph theory is used in different areas which provides a powerful tool to model these direct and indirect interactions. The Effect graph is constructed for the Agro- ecosystem taking vertices as the elements of ecosystem and connected by the edges that correspond to the interactions between them with the weights’ representing how strongly these elements effect one another. Using Graph theory concepts some of the cases when one of the factors is eliminated from the ecosystem and if there is an undesirable increase of amount of one of the factors of the ecosystem are discussed by Effect graph. To find the cheapest and fastest possible ways of increasing the yield by Floyd’s algorithm which gives the shortest path for a graph structure.
