&lt;p&gt;&lt;b&gt;New page&lt;/b&gt;&lt;/p&gt;&lt;div&gt;==task1==&lt;br /&gt;
&lt;br /&gt;
well there are 9 squares so apparently there will 9! states. &lt;br /&gt;
&lt;br /&gt;
To estimate the number of edges in the complete state space graph, we need to calculate the number of posible squares the &amp;quot;space&amp;quot; can go from every single square of 3x3 grid.&lt;br /&gt;
&lt;br /&gt;
I had no idea how to calculate it. I got help from this guy in the lab.&lt;br /&gt;
*if the space is in the corners it has 2 posible choices and there are 4 corners.&lt;br /&gt;
*if it is in the middle it has 4 choices.&lt;br /&gt;
*if it is goes to left or up from the corner, it has 3 choices from that position and there are 4 square with 3 choices.&lt;br /&gt;
(4*2)+(4)+(4*3)=24&lt;br /&gt;
&lt;br /&gt;
Then you divide that by 9 since there are 9 grids. 24/9=2.67 and since there 9! states, times the answer by 9! and since we have repeated the choice twice, we divide it by 2. &lt;br /&gt;
&lt;br /&gt;
So, the answer is... 9!*2.67/2=483840.&lt;br /&gt;
&lt;br /&gt;
There are 483840 edges in the complete stae space graph.&lt;br /&gt;
&lt;br /&gt;
==task 2==&lt;br /&gt;
I am not sure what&amp;#039;s going on here.&lt;br /&gt;
&lt;br /&gt;
==task 3==&lt;br /&gt;
&lt;br /&gt;
With the help of the tutor, I figured out how to draw the graph. I checked it with the file graph.c and it looks the same :)&lt;/div&gt;</summary>
