Option-Pricing-via-Levy-Models-in-R | Transform method to speed up options pricing simulations

For example, I want to randomly line the 0, 1 (50% respectively) 10 times. So, there should be five "0" and five "1".

But, when I used:

I was simulating the solar system (Sun, Earth and Moon). When I first started working on the project, I used the base units: meters for distance, seconds for time, and metres per second for velocity. Because I was dealing with the solar system, the numbers were pretty big, for example the distance between the Earth and Sun is 150·10⁹ m.

When I numerically integrated the system with scipy.solve_ivp, the results were completely wrong. Here is an example of Earth and Moon trajectories.

But then I got a suggestion from a friend that I should use standardised units: astronomical unit (AU) for distance and years for time. And the simulation started working flawlessly!

My question is: Why is this a generally valid advice for problems such as mine? (Mind that this is not about my specific problem which was already solved, but rather why the solution worked.)

I try adding a new variable that has an association with the previous one. Is there a math/code trick/formula to increase the width of confidence bands in this association?

i made a function in unity that takes a Binode - and making it into a2d tree, but here the problem: my so called idea to display the tree is this:

make a recursive function, and every time the level will go up by 1, and it will also send the function a bool(is the right or is the left of the old node) and then if its true it will get the root of the tree and - the y by level * 55, then it will either x = level * 55, if it right, and if its left the x = level * -55.

now the problome is lets say i have a tree that has 3 levels, then if i will put a right node to the left tree it will just put it were the most right node is and it will overlap, kinda hard to explain in text but i hope you understand.

code:

In my model I use a transporter which uses free navigation. If it is right, the transporters can not move through walls, the strange thing is that in my model at one point somehow the transporter is able to move through a wall?

He slips through the wall somewhere at the red circled section, when I check the simulation. (see screenshot, blue is the transporter)

When I look at the model, I also see that there is no gap or something (see second image). Am I'm overlooking something (maybe something about that I've multiple floors)? or is it a bug? Does somebody know how to fix it.

I'm having difficulty finding the documentation I need to work with Resources and resourcePools - there is no "resource API documentation" that I can find.

I would like to programatically create static resources (of a custom type) and then add these resources to a resourcePool. When creating the resources, I'd like to be able to specify their property values prior to adding them to the resourcePool. In my mind the code would look something like this:

I've got another small issue with AnyLogic resources.

I want to be able to release a specific resource from a resource pool - not just any resource from the pool. The reason is that I occasionally seize multiple resources from a ResourcePool (one at a time) and then wish to release the resources again one at a time. But I don't want to release "any" resource from the pool, I want to be able to specify which specific resource of the pool to release.

Is this possible or is this one of the limitations of the resources implementation?

I would like to use transporters in my model in various places (tugboats, forklifts, reach stackers, trucks, etc.). However, my model paths and animation can't be drawn to scale, detailed explanation in brackets below. Is there a way I can move the transporter from one node to another based on travel time (similar to what a movable resource can do), rather than speed and distance? The "Move By Transporter" block does not seem to allow this and I have not been able to find a solution online. Thank you for your help.

(Explanation on why I can't draw to scale: firstly, some destination locations (storage areas, etc.) are not known yet and will just be represented by a travel delay to get there, secondly, different areas of the model will be drawn to different scales, i.e. some network paths will represent a multiple kilometers and some network paths will only represent a few hundred meters, etc.)

I collect various data in time plots. If I copy the timeplot data and then paste it into Excel, the number format is often wrong. For example, I often get a date like Aug 94 instead of the actual number from the TimePlot. Unfortunately, I can't easily format this date into a number either, since the formatted number does not match the actual number from the timeplot. If I format the date in the same format as the number above and below, then I get the number 34547. However, this number does not correspond to the actual number of the TimePlot. Anyone know how I can prevent this problem?
