bouncingball | Visualizes gradient descent techniques on functions | Machine Learning library

I want to be able to align my widget to the top of the screen.

What my code is doing right now is that it starts from the center which is this portion of the code:

I'm trying to implement a recursion solution for a Codewars problem. I don't see where I am going wrong. Can this problem even be solved using recursion?

I try to run python script, but i got error in line, where i used ModelicaSystem, but i don't understand how to fix the problem

I have built and started an OPC UA embedded Openmodelica server with the BouncingBall model like so:

So, here is one of the most basic script you can run in OMShell:

My bouncing ball is meant to bounce between 200x200 window's borders. I'v managed to make him stop and change direction when he touches the right and bottom borders. But when he reaches the top and left borders, a 1/4 of the ball goes through the border and only then it changes direction.

I have no idea why it happens, I mean it's literally the same code lines for each border. How can it even be that for the same code it will work differently?

I went through lots of codes around the net about this topic, and tried every solution or code, and it's still stays the same.

Thanks.

Why does this solution work? most people are doing loops to solve this and i did recursion, but this is easy as hell, for the computer, i am so confused why does this work?

Description: A child is playing with a ball on the nth floor of a tall building. The height of this floor, h, is known.

He drops the ball out of the window. The ball bounces (for example), to two-thirds of its height (a bounce of 0.66).

His mother looks out of a window 1.5 meters from the ground.

How many times will the mother see the ball pass in front of her window (including when it's falling and bouncing?

Three conditions must be met for a valid experiment: Float parameter "h" in meters must be greater than 0 Float parameter "bounce" must be greater than 0 and less than 1 Float parameter "window" must be less than h. If all three conditions above are fulfilled, return a positive integer, otherwise return -1.

Note: The ball can only be seen if the height of the rebounding ball is stricty greater than the window parameter.

I'm learning to work with java threads, so I decided to make a simple bouncing balls program. However, the program shows multiple threads but only one takes advantage of the window size, other balls are restricted to one area.

I tried setting the size for each balls' JPanel and different layouts which didn't work.

I'm working on animation of moving balls, which must collide with walls and with each other. Half the work is done. Balls already can collide with walls. But I don't know how to make a collision of balls with each other. I tried using the loop throughout the ArrayList collection, but the balls are removed incorrectly. Maybe you can help me with this task.
