JLog - Prolog in Java Browser users can click on the example hyperlinks, or open the URLs in another Java environment. To try an example, From the Consult pane, click on the Consult button which appears at the lower right of the Source text area. When the consultation completes, click on the Query tab at the top. The Query panel appears. Click on the Query button to the right of the Query text field. The following examples show JLog in action: Queens, a program to solve the classic queens problem where we try to place N queens on an NxN chess board without any queen attacking another. Belief Networks, a program which calculates the likelyhood of an event given the occurance state for an event, and a propabalistic graph of the the causal relations between events. A fire alarm example is provided. Constraint Satisfaction, a program which implements a constraint satisfaction solver where variables must satisfy restrictions between other variables and must be instances of their domain. A scheduling example is provided. Neural Network, a program which learns parameterized logic using back-propagation in a neural-net approach. A example is provided to learn the reading preferences of an author. Robot Simulator, A program that simulates the motion of a goal oriented, reactive robot in a simple environment. The robot is a small car with a whisker. The robot turns to move in the direction of its next goal, but when the whisker touches a wall, the car turns to avoid it. The example includes an animation of the robot's progress in the Animation panel and a sample environment. This example uses the autorun feature of JLog to automatically consult, query, and set the visible pane. The animation should appear running when the applet loads. Definite Clause Grammar, A program that demonstrates the DCG support in JLog. Includes the grammar for a simple arithmetic expression.
