Following default Maven project layout.

This will merge in Ruediger's individual Vacuum and Map application demos, 
into a single demo that show cases the different algorithms implemented 
from aima-core.

Currently thrree projects exist:

aima-core
aima-gui
aima-all

Ant build.xml files need to be setup to build and manage the project 
interdependencies. aima-all is the top project intended for developers and 
will be the one for pulling all other aima projects together and releasing 
as a cohesive set of jars and zip files.

aima.core.gui.demo.logic.FolDemo is the current command line demo

aima.core.gui.demo.logic.TTEntailsDemo is the current command line demo

What steps will reproduce the problem?

 Just run the N-queens demo.

What is the expected output? What do you see instead?

 Some search steps, it does nothing.

What version of the product are you using? On what operating system?

 Doesn't matter.

Please provide any additional information below.

 When you changed the heuristic functions from int to double you didn't
notice that the meaning of Integer.MIN_VALUE and Double.MIN_VALUE are not
the same. In order to HillClimbing algoritm to work you have to use
Double.NEGATIVE_INFINITY instead.

Comment by russ.abbott, posted to ReadMe Wiki 10/10/09:

In Search, it would be nice to see the states as well as the actions. 

That can be done easily enough by modifying 

aima.search.framework.searchUtils.actionsFromNodes() to be as follows. 

  public static List<String> actionsFromNodes(List<Node> nodeList) {   
     List<String> actionList = new ArrayList?<String>();   
     for (Node node: nodeList) {     
         actionList.add(node.getAction() + " ==>\n" + node.getState());  
     }   
     return actionList; 
  }

What steps will reproduce the problem?
1. Download the eclipse project.
2. Import into workspace.
3. Allow it to finish building.

What is the expected output? What do you see instead?

The Eclipse project should build correctly when first imported. It does not
build correctly because of a dependency on the following jar in the
.classpath file:

    <classpathentry kind="lib"
path="/home/ravi/projects/java/javalibs/junit3.8.2/junit.jar"/>

This entry should be replaced by the following entry:

    <classpathentry kind="con"
path="org.eclipse.jdt.junit.JUNIT_CONTAINER/3.8.1"/>

assuming that the JUnit tests are compatible with 3.8.1. This will
eliminate the errors initially seen after import.

What version of the product are you using? On what operating system?

Latest version, Windows, Eclipse 3.2

Fig 14.10 Elimination-Ask

Fig 23.5  CYK-Parse

What steps will reproduce the problem?
1. use default test in dpll demo
2. extend any of the alternatives by one more literal
3. watch how everything turns into dust :D

What is the expected output? What do you see instead?
well it should work, instead "Exception in thread "main"
java.lang.RuntimeException: Syntax error detected at match. Expected ) but
got OR" in main and all parsers.

What version of the product are you using? On what operating system?
win xp under fresh install of java sdk but checked it on other sdk versions.

Please provide any additional information below.
any idea when it shall work? thx in advance for your help.
