Therefore, the mathematics of maze design is just as applicable in modern, dementia-battling apps as it was in distant Greek mythology. We “reverse-engineered” intelligibility in order to produce game levels that were more, or less, maze-like, to ensure a range of challenges for the players. It was this measure of intelligibility that we used to design the game levels in the recent SeaHeroQuest game, a game designed to measure people’s navigational skills in order to further dementia research. The measure ranges from 0 to 1: environments that score highly (greater than 0.5) tend to be quite intelligible, easy to understand and navigate, and frequently desirable – for example Barnsbury, in London.Ĭonversely, places with a low intelligibility score tend to be confusing, hard to navigate and, ultimately, maze-like – London’s Barbican Estate, although architecturally lauded, is so confusing that visitors need to follow the yellow lines in order to find their way around. To answer this, Hillier developed the measure of “intelligibility”, which is the relationship between what is immediately visible from a single location in a maze/housing estate/neighbourhood and how accessible that same place is from other locations in the area.
Mazes are fun, but are not necessarily something we want in our everyday lives – or in our way when we just want to get to work.īarnsbury, in London: extremely unmaze-like. So how is any of this maze stuff useful? Well, from the perspective of architecture and urban design, we want to avoid accidentally creating mazes.
This method is guaranteed, eventually, to get you out of any maze. The cardinal rule is never, ever select a path already containing two trails. And if choosing between a once or twice-used path, choose the path used once, then leave a new, second trail behind you. If that leads you to a junction where one path is new to you but the other is not, then select the unexplored path. Imagine that, like Hansel and Gretel in the fairy story, you are able to leave a trail of “breadcrumbs” behind you as you navigate your way through the maze and then remember these rules: if you arrive at a junction you have not previously encountered (there will be no crumbs already on the trail ahead), then randomly select a way to go. Most methods work for “simple” mazes, that is, ones with no sneaky short-cuts via bridges or “passage loops” – circular paths that lead back to where they started. There are techniques for escaping from mazes, but first you need to be sure what kind of maze it is.

The algorithms tend to fall into two principal types: ones which start with a single, bounded space and then sub-divide it with walls (and doors) to produce ever smaller sub-spaces and others which start with with a world full of disconnected rooms and then demolish walls to create paths/routes between them. While designing a maze can be a rewarding human task, computer scientists and mathematicians have a love of maze-generating algorithms. Escape latency decreased over the four trials, both in the WT and the APP/PS1 Figure 1A day 1: two-way repeated measures ANOVA: training effect: F (3, 51) 13.78, P < 0.0001 genotype effect: F (1, 17) 1.806, P 0.1966 interaction: F (3, 51) 3.105, P 0.8177. Which begs the question: what is the difference between a maze and a labyrinth? Although considered synonymous by some, it is generally accepted that a labyrinth contains only one path, often spiralling around and folding back on itself, in ever-decreasing loops, whereas a maze contains branching paths, presenting the explorer with choices and the potential for getting very, very lost. The mice were trained on day 1 on the cued water maze. But mazes have been around for millennia and one of the most famous mazes, the Labyrinth home of the Minotaur, plays a starring role in Greek mythology.

Improved performance was seen, however, if a second injection of midazolam was given before the second escape, suggesting a state-dependent effect.Mazes are in vogue at the moment, from NBO’s Westworld, to the return of the British cult TV series, The Crystal Maze. Chicks given midazolam (0.1 or 0.3 mg/kg, IP), a benzodiazepine, before the first escape, showed no improvement on their second escape. Undrugged chicks always showed significant improvement in task latency if they were replaced in the maze 3 hours after a successful escape, suggesting that they had remembered the task. On a subsequent trial, any improvement in the speed of performance was reasoned to reflect the chick's memory of the task. When the chick successfully negotiated the corridor, the latency to perform this task was recorded. A 'T' corridor, or maze, connected the isolation chamber to the brood space, allowing the chick to escape isolation stress and rejoin the brood. Chicks were separated from their brood mates and placed in a small isolation chamber. We report a simple, one-trial, learning paradigm which we have developed for use in young chicks.
