`<param>` (Parameter)

The parameter element modifies the default behavior of an algorithm.

example:

<alg type="snake">
	<param type="grDir" val="tL"/>
	<param type="flowDir" val="row"/>
	<param type="contDir" val="sameDir"/>
	<param type="off" val="ctr"/>
</alg>

In this example we see the snake algorithm being utilized and four parameters being set which are associated with the snake algorithm and modify its behavior. ]
