ECOLOGICAL TOOLS

This online service contains ecological algorithms involving in statistics, ecology, control theory, differential equation, optimization, decisionmaking, game theory, etc. You can simply click any algorithm listed in the following to run it on web browser.
Before using this package, the security preference for running java or java applet on browser should be set to a lower level. The best browser to run the package is HotJava Browser. The certificates for running it on other web browsers, e.g., Netscape Navigator and Microsoft Internet Explorer, will be applied whenever the related conditions permit.
Each software in this package is a Windows program which includes several interfaces. Help interfaces and the interfaces for saving result and graph are also included.
