Different how? Even humans are constrained in their decision-making.
Human is constrained by options. He however is to choose an option freely. We need the freedom to decide when the options are equally liked. You are free to decide because things are indifferent to you.
Skepdick wrote: Mon Mar 30, 2020 8:22 am In fact - unconstrained decision-making is impossible. Even you can't enumerate a set of infinite options, let alone choose from such a set.
You are fully aware when you make a decision.

You can't explain what the word "freely" means....

How do you decide between "equally liked options" except rolling a dice? e.g random choice - entropy.

So is the algorithm - it's aware of all the possible options.

What you are talking about has a name in computer science: control flow.

I did. It is when you minimally like options equally. Or even when you go for the option you don't want for no reason.

I just do it. It looks random from third perspective but not from the first perspective.

Everything is conscious. Consciousness is needed for any change. I however don't think that computer is conscious like us.

This is incoherent.

To like all options equally is the same as to like all options at the same level of minimality.
If you "go for the option you don't want" it means you want the other option even less.

Non-deterministic algorithms are all about 1st person perspectives. From the POV of the algorithm the choice is random.

"Just pick any one". It seems that's exactly what you are doing.

You are just tripping up over the discretisation.

Either infinitesimals have a lower bound in which case there is finitely many of them between 0 and 1.
Or they don't have a lower bound in which case there's infinitely many of them between 0 and 1.

Things has absolute length therefore there is a lower bound so called infinitesimal. The length L by definition contains L infinitesimals.

Everything has an absolute length. That is why we can measure them. We use a good constant to assign a standard length to things.

The true unit is infinitesimal. We don't have access to it so we use other thing which are made of infinitesimal.

OK, but the length is always divisible by 2. Hence your problem.

So the Integer 1. Which is indivisible by 2 (if the division is to be closed).

It's as "freely" as you are doing it. That's why it's non-deterministic to the programmer.

Of course I do. I choose the thing which maximises my utility, whatever that may be given my utility function.

The "absolute length" of the 1st integer is 1 - its distance from 0.

Exactly. Dividing 1 by 2 is open, not closed e.g the answer is not in the domain of the integers.

What you are really asking is how one can get a "continuum" from discrete elements. The simple answer is - you can't.

Mathematics is discrete because language is discrete. On metaphysical level - language is discrete because time is discrete. Humans think in beginnings and ends. Physics is discrete because a "measurement" is an effect on the measurement apparatus caused by the thing being measured.

If physics was "continuous" you can't have things like "causes" and "effects" - you'll just have a function.

Physical entities are discrete, and, you are right that language and mathematics are discrete (a very astute and correct observation, by the way). But all physical relationships are analog, which is why no mathematical measurement is ever absolutely exact (except by accident) because measurement is in terms of arbitrary discrete units of measure.

There is no physical infinitesimal (or infinite) which are only the extremes of arbitrary (human invented) units of measure.[/quote]
