Game of life golly ticker

Each cell can be either alive or dead. The status of each cell changes each turn of the game also called a generation depending on the statuses of that cell's 8 neighbors. Neighbors of a cell are cells that touch that cell, either horizontal, vertical, or diagonal from that cell.

The initial pattern is the first generation. The second generation evolves from applying the rules simultaneously to every cell on the game board, i. Afterwards, the rules are iteratively applied to create future generations. For each generation of the game, a cell's status in the next generation is determined by a set of rules.

These simple rules are as follows: If the cell is alive, then it stays alive if it has either 2 or 3 live neighbors If the cell is dead, then it springs to life only in the case that it has 3 live neighbors There are, of course, as many variations to these rules as there are different combinations of numbers to use for determining when cells live or die. Conway tried many of these different variants before settling on these specific rules. Some of these variations cause the populations to quickly die out, and others expand without limit to fill up the entire universe, or some large portion thereof.

The rules above are very close to the boundary between these two regions of rules, and knowing what we know about other chaotic systems, you might expect to find the most complex and interesting patterns at this boundary, where the opposing forces of runaway expansion and death carefully balance each other. Conway carefully examined various rule combinations according to the following three criteria: There should be no initial pattern for which there is a simple proof that the population can grow without limit.

There should be initial patterns that apparently do grow without limit. There should be simple initial patterns that grow and change for a considerable period of time before coming to an end in the following possible ways: Fading away completely from overcrowding or from becoming too sparse Settling into a stable configuration that remains unchanged thereafter, or entering an oscillating phase in which they repeat an endless cycle of two or more periods.

Example Patterns Using the provided game board s and rules as outline above, the students can investigate the evolution of the simplest patterns. They should verify that any single living cell or any pair of living cells will die during the next iteration.

Some possible triomino patterns and their evolution to check: Here are some tetromino patterns NOTE: The students can do maybe one or two of these on the game board and the rest on the computer : Some example still lifes: Square : Boat : Loaf : Ship : The following pattern is called a "glider.

A glider will keep on moving forever across the plane. Another pattern similar to the glider is called the "lightweight space ship. Early on without the use of computers , Conway found that the F-pentomino or R-pentomino did not evolve into a stable pattern after a few iterations.

In fact, it doesn't stabilize until generation The F-pentomino stabilizes meaning future iterations are easy to predict after 1, iterations. The class of patterns which start off small but take a very long time to become periodic and predictable are called Methuselahs. Want a good read?

One more small cleanup, forgotten yesterday. Smallest GoE. Marijn Heule, Christiaan Hartman, Kees Kwekkeboom and Alain Noels systematically searched the entire space of by patterns with fourfold rotational symmetry, finding a Garden of Eden with 92 specified cells 56 live, 36 dead.

Moreover, they proved the non-existence of Gardens of Eden within a 6-by-6 box. If you asked a fellow Life enthusiast for the most important GoL discoveries in the s, the Herschel track must surely feature.

With a few elementary conduits, it is possible to design tracks capable of moving a signal to anywhere in spacetime as long as there is enough 'manouevring room' and sufficient time , and placing it in any orientation. Herschel tracks underpin all but two of the known stable reflectors, and support the construction of glider guns for every period greater than or equal to Flow matrix for five common transient objects.

Firstly, what is so special about the Herschel? Is it really so much more useful than any other transient objects? It appears that the answer is both yes and no: other objects can be used, but they must eventually decay into Herschels. This is illustrated rather eloquently by a simple matrix. The row represents the input; the column represents the output. A red blob indicates if a primary one-stage conduit exists to transform the input into the output. Clicking on the matrix will enable you to download a complete collection of primary conduits.

A collection of all conduits, primary and composite, is provided later in this article. Guam's generation left-turn conduit. Some of these conduits are new discoveries. The Pi-to-R converter was discovered by Guam on the conwaylife. The completed conduit takes generations to turn a Herschel anticlockwise, so is designated L In terms of the number of intermediary objects, L is the most complex Herschel conduit to date.

Indeed, its tick delay is rather rapid for a quaternary conduit. Isomers of Guam's tick Herschel conduit. Not content with a single new conduit, Guam proceeded to discover a pi-to-Herschel converter capable of attaching to a handful of 'pre-Herschel' conduits. Moreover, the symmetry of the pi heptomino means that Guam discovered not only one conduit, but two 'isomers'! The conduits are designated F and Fx for the translation and glide-reflection variants, respectively. Matthias' tertiary Herschel conduit, the Lx From an earlier posting of mine, you may remember the contributions of a certain 'MikeP', again from the conwaylife.

Matthias Merzenich has utilised a particular catalyst of his in a few conduits, including the periodic R conduit and a stable Pi-to-century converter. To process the resulting century, Matthias proceeded to find two unique century-to-Herschel converters, one of which is sufficiently compatible to yield a new tertiary Herschel conduit, the Lx Matthias even found a use for this new inundation of Herschel conduits; he has incorporated them into glider guns with smaller dimensions than the current record-holders.

Specifically, they are a p gun derived from the L and p gun based on the Lx Guam's 4hd Herschel receiver. In addition to his spectacular Herschel conduits, Guam also found two reactions in which gliders collide with constellations of still lifes to form extra junk. We already have a glider-to-beehive and glider-to-block converter, virtue of Paul Callahan, but we can now add loaves and bi-blocks to the collection. The latter is especially interesting, as a glider in the same direction as the original can liberate the bi-block in the form of a Herschel.

The gliders are separated by 4 half-diagonals, unlike in previous receivers, where the separation must be 2, 5 or 6; hence, this new receiver could function where others fail.

Also, it transpires that the bi-block functions as a LWSS eater , which can be toggled by incoming gliders.

Finally, he noted that two gliders separated by 4 or 5 half-diagonals can be reflected into a single glider. Here it is demonstrated as part of a stable reflector and related pulse divider. Alas, this reflector does not break any records, unlike the next subject of discussion -- the rectifier.

This fast reflector, subject of a previous article on LifeNews, can be used in various conduits for transforming Herschels into gliders, by either modifying the output or assisting in the cleanup of surplus blocks. To summarise this article, here is a collection of the 30 distinct Herschel conduits including four adjustable ones , and a comprehensive collection of every sufficiently simple conduit, transceiver and converter known, as of the time of writing.

Of course, an infinite number of spaceship velocities are known, as the Gemini can be adapted accordingly. Moreover, Matthias has actually discovered an infinite family of such spaceships, as one of the frontal components can support itself to yield an extensible spaceship.

As we've been busy recently, there have been no LifeNews postings for the last couple of months.
