Blackjack strategy: Difference between revisions

 

Assume that my casino:

* What can I expect to be my biggest loss?

* What can I expect to win/lose over the year?

=={{header|Go}}==

As the dealer plays automatically, the first thing I did was to write a function which calculates the probabilities of the dealer ending up with various scores according to the Rules. I then checked the resulting table against a similar one on an 'active' online gambling site (which I'd better not link to here) and the results agreed to 6 decimal places.

 

Finally, I've done 10 years of simulations as the basic statistics can vary quite a bit from year to year. However, it will be seen that % loss varies over a narrower range - between about 0.3 and 1.8% for this particular run - which seems reasonable given the casino's edge even after basic strategy is utilized.

 

import (

Loss % staked : 1.801

</pre>

=={{header|Nim}}==

{{trans|Go}}

 

type

Total staked: 20516.0

Loss % staked: 0.453</pre>

=={{header|Phix}}==

</pre>

=={{header|Wren}}==

{{trans|Go}}

{{libheader|Wren-dynamic}}

{{libheader|Wren-fmt}}

<br>

This runs OK but takes a long time to do so - 6 minutes 21 seconds compared to less than 3 seconds for the Go example. As I also wrote the latter I'm confident it's a faithful translation.

 

So interpreted languages such as Wren are probably stuck with slow times for this task.

import "./dynamic" for Struct

import "./fmt" for Fmt
