The reason why Python is the most popular with AI developers is that it's the easiest or versatile programming language among all the current known programming languages. Additionally, it has such a large library. If you have got fundamental concepts of CS shared across all programming languages, it will take from only 1 days to a few days to master Python's syntax

Want to clarify for those hard of understanding on the arc matrixes and sudoku, that (linear programming) Action1 has cost1 because of X1 Math, A2C2X2, etc = A contains: B contains: [ X [ X Y Y Z ] Z ] These are two separate matrices so duplicates are okay, if they are both nested into a single matrix than they cannot contain the same so if A = XYZ, and B = ABC but I want to switch A = X with B = C I have to backtrack to get than switched so that anything afterword can have it's proper Alignment (If I am on D I have to go all the way back to B and switch) This counts as An Action1/Cost1/X1 move for example, if your AI was trying to cycle through all the matrices and properly align them. The reason that you don't want duplicates in a single matrix is the same as in geometry that a straight line is the shortest path between towns, If I start From: X then Y then Z it is in sequence, If I reverse it, it's still in sequence. But if I change X then Z Then Y, (Z) is in the center meaning I must go from X to Y to Z (sequence), then back to Y, because I had to pass through Y to get to Z in the middle anyway. (like I need to go to Walmart, Mcdonalds, and Kohls but I go to kohls first so I have to drive all the way back to Mcdonalds etc etc) Everything else was pretty good for such a long video very precise but that part got a little repeat confusing I think. BTW, since this is all costly one should use both breadth and depth - first searches with A* to get to the goal faster from both directions, so that things like this matrix can be solved with inference (if A = XYZ THEN C must = ABC) faster, in order to produce sequential inference actions faster. It's If, Then logic is what inference means: If A, then B.

min 2:10:36 if Harry didn't visit Hagrid does not imply that it rained. The sentence says that if it doesn't rain, then Harry visited Hagrid. The statement does not suggest that there is a codependancy between not visiting Hagrid and raining. There is not even a dependancy between raining, and doing anything. We know that Harry visited Dumbledore and didn't visit Hagrid. That is a fact. But, we can't conclude that it rained today.

Learned a lot from this video. Two thumbs up. For the specific example he gave, the number tile, I think "reverse engineering" approach, couples with the AI process he described, will solve the problem more efficiently. That means I start with the end sequence = numbers in ascending order left to right, top to bottom. Then I map out all possible paths to "chaos" state = all tile arrangements that are not the end sequence. I can determine all possible chaos states = 16! = 2.092279e+13 assuming the hole is also a tile. The possible paths should be much less than 16! because each move along the way to a most "severe" chaos state is a chaos state itself. The map will look like a family tree, starting with the end sequence, and the last progeny of each branch is the most "severe" chaos. When user enters a chaos state, the algo finds where it is on the family tree, follow the reverse path/moves back up to the end sequence. The reverse-engineering approach will only work well when the goal/end is well defined.

Also wanted to say that probability is not calculated in A^^2/[A^^2 + B^^2] but is instead calculated without powers as either 1 with ratios or done Just as A/[A + B] with their associative numerical values, but there is a lot of ways to calculate probability. The reason people put a ^^2 on to it is to mathematically express it has a Min/Max values that varies between themselves and the square is supposed to be the maximum value. Other people will use 1/2 * A^^2 for example which is also pretty irrelevant. Because you are actually just getting the ratio value of 1/[2+5] = 7 and getting the reciprocal which is the same as 1/2 = 0.5 which is the ratio of 1 to 2.

This brought good memories of a course I took in 1989 while doing my computer science degree. We did the same algorithm and many similar ones. For the first one, the maze, we used a recursive algorithm or loops, traversing graphs and trees. I did not know we were doing AI at that time :) In fact, this is not AI, but without the AI attached to the name, people may not watch the video.😁 This video is fantastic as it illustrates the power of optimizing algorithms to improve performance. The time complexity of such an algorithm as the maze is exponential.
