World templates

The templates aims to cover the most common worlds that user would possibly wish to simulate. There is no environment template which would not be possible to define using the standard definition.

The syntax is

WORLDdefinition -quick = keyword size

The interpretation of all possible keywords and the parameter size is in the table bellow. An instance of World is in the simulation a grid of demes. Given the nature of simulation, we have to specify what is happening with individuals on the edge of the world. The simulated hybrid zone have two infinite populations on the left and right respectively. Therefore type of left-right edges denotes a contact with infinite populations and type of up-down edges in the grid is only solving a limitation of finite simulation. The full description of edge types in page World.

KeyWord	Dimension	Number of demes in column	Type of UD edges	Number of columns	Type of LR edges

LowMigrationBazykin	2	1	’reflective’	2	’extending’
Arena	1 - 2	size	’reflective’	size	’reflective’
