Banko is a game of chance, often played in a social setting. It is somewhat similar to the U.S. variant of Bingo, but has its own rules. The basics is that each player has one or more banko cards -- each card having 15 numbers -- and must cover a set amount of randomly picked numbers to win, at which point they yell "BANKO!".
For this talk I want to first explore existing problems related to scaling banko games, quickly discover that none exist, and then spend the remaining time describing made-up problems and solutions to them.
In particular, the umbrella term 'Big Banko' covers such diverse areas as:
Standardisation: How do you transfer banko cards between different entities and not get confused? I present a well-defined and open banko card standard.
Visualisation: What is the most human-friendly non-print visualisation of one or more banko cards? I showcase several approaches and pick the best one.
Validation: When you're in a hurry, how do you quickly check the validity of millions of banko cards? I present a GPU-accelerated solution that outperforms a human by several orders of magnitude.
Compression: Just how much can you compress (the digital representation of) a banko card? Whenever someone needs to transfer billions of banko cards over a slow internet connection, they need a fast and reliable compression/decompression scheme. There are several low-hanging fruits in the quest for a good lossless compressor, but it is a surprisingly complex and math-dense endavour to exploit all the banko card invariants and reach optimality. I present a variety of algorithms and discuss their bit usage.
Simulation: Is it possible to remove the human element from banko altogether, and just let a computer play it? Yes, of course it is.
This talk is introductory in nature and is suited for all audiences, including:
- intermediate banko enthusiasts wanting to gain an edge;
- banko business-doers wishing to modernise their enterprises; and
- banko newcomers working on becoming cool.
The contents of the talk will occasionally require a good understanding of computer science, but I will make sure to always give the big picture as well.
