Inoculation

ancestor (type: enumerated, range: {a1,a2,user_defined})

Specifies the ancestor(s) programs to be used for inoculation. There are two predefined ancestors (a1 and a2, listed in Section A.3). If user_defined is specified, the ancestor(s) are read from the file ancestor.ini. The format of this file is described in Section A.5.

number (type: non-negative integer, range: 1-10000)

The number of individual programs to inoculate the system with at the start of the run. If more than one type of ancestor is specified in the ancestor.ini file, these are introduced alternately until a total of number individuals is reached. If the parameter placement is set to even, then the actual number of inoculated individuals may be slightly smaller than that specified by number (see description of placement for details).

placement (type: enumerated, range: {even,random})

Determines the placement of the inoculated ancestors. For even placement, the ancestors are placed evenly on the grid in a square pattern, where the sides of the square are as close as possible to the square root of the number specified by the parameter number. If number is not a square number, the actual number of individuals will therefore be slightly less than specified. For random placement, individuals are placed completely randomly, and no check is made to see whether the chosen position is already occupied.
