The Bio-PEPA Eclipse Plug-inUser Manual: Parameter Definitions

A.3 Parameter Definitions

The concrete syntax for parameter definitions, as accepted by the plug-in, is as follows [14]:

$\begin{array}{r} ID = expression; \end{array}$

where

$\begin{array}{r} expression = \; int \; | \; float \; |\; ID \; |\; speciesID \; |\; (expr ) \; |\; expr + expr \; |\; \\ expr - expr \; |\; expr /expr \; |\; expr * expr \end{array}$

An $\text{[math]}$ is any standard mathematical expression with the definition structured as it is because of the recursive nature of the expression ( $expr$ is an abbreviation for expression, and not a different set of allowable expressions). Also, $speciesID$ must refer to a species in a single location if multiple locations are specified [14]. Some examples of parameter definitions are shown below:

`r`	`=`	`1.0;`
`r`	`=`	`A - B;`
`r`	`=`	`A@main + B;`

where $A$ , $A@main$ and $B$ are $speciesID$ s.
