When Search Result printed Action list is now in reverse order (in v1.0.0.rc2 vs v1.0.0.rc1)

[gahrae]

When a Search Result is printed it displays a list of actions.

In version v1.0.0-rc1 the list of actions could be read left to right. Now in v1.0.0-rc2 the list needs to be read right to left. I believe that the actions should appear in the list in sequence from left to right.

// To print a search result..
System.out.println( Hipster.createAStar(problem).search(predicate) );

For example, below is a completed Hidato board. It starts at 1, then moves to 2. The action that describes this step is MOVE_UP.

Completed Hidato board...
11 10  <2>  3 
12  9  [1]  4 
13 16   8   5 
15 14   7   6 

Below is the printed search results from version rc1 and rc2. Observe that the first action of MOVE_UP now appears at the end of the action list in the version rc2 output. And that the action list is now in reverse order.

rc1 output - Action list in correct order, left to right

Total solutions: 1
Total time: 77
Total number of iterations: 398
+ Solution 1: 
 - States: 
    [(2,1)=1, (2,0)=2, (3,0)=3, (3,1)=4, (3,2)=5, (3,3)=6, (2,3)=7, (2,2)=8, (1,1)=9, (1,0)=10, (0,0)=11, (0,1)=12, (0,2)=13, (1,3)=14, (0,3)=15]
 - Actions: 
    [MOVE_UP, MOVE_RIGHT, MOVE_DOWN, MOVE_DOWN, MOVE_DOWN, MOVE_LEFT, MOVE_UP, MOVE_UP_LEFT, MOVE_UP, MOVE_LEFT, MOVE_DOWN, MOVE_DOWN, MOVE_DOWN_RIGHT, MOVE_LEFT]
 - Search information: 
    WeightedNode{state=(0,3)=15, cost=14.0, estimation=1.0, score=15.0}

rc2 output - Action list in reverse order, right to left

Total solutions: 1
Total time: 78
Total number of iterations: 398
+ Solution 1: 
 - States: 
    [(2,1)=1, (2,0)=2, (3,0)=3, (3,1)=4, (3,2)=5, (3,3)=6, (2,3)=7, (2,2)=8, (1,1)=9, (1,0)=10, (0,0)=11, (0,1)=12, (0,2)=13, (1,3)=14, (0,3)=15]
 - Actions: 
    [MOVE_LEFT, MOVE_DOWN_RIGHT, MOVE_DOWN, MOVE_DOWN, MOVE_LEFT, MOVE_UP, MOVE_UP_LEFT, MOVE_UP, MOVE_LEFT, MOVE_DOWN, MOVE_DOWN, MOVE_DOWN, MOVE_RIGHT, MOVE_UP]
 - Search information: 
    WeightedNode{state=(0,3)=15, cost=14.0, estimation=1.0, score=15.0}

I believe that the actions should appear in sequence from left to right as in rc1.

Best regards,
