Identifies an set of piecewise linear additive value functions according to a ranking of the alternatives. If the number of segments is not given, a general additive value function is looked for.

(For outputs, see below)
Threshold value indicating the minimal difference in terms of the overall value between two neighbor alternatives in the given ranking.
The input value should be a valid XMCDA document whose main tag is <methodParameters>. It must have the following form:
<methodParameters>
<parameter
name="separationThreshold"><!-- REQUIRED -->
<value>
<real>%1</real>
</value>
</parameter>
</methodParameters>
where:
%1 is a parameter named “separationThreshold”. This is a float, and the value should conform to the following constraint: The value should be a strictly positive float, less than the highest possible overall value.. More formally, the constraint is:
%1 > 0
The number of segments for the additive value functions. If it is not given, then a general additive value function is searched for.
The input value should be a valid XMCDA document whose main tag is <methodParameters>. It must have the following form:
<methodParameters>
<parameter
name="criteriaSegments"><!-- REQUIRED -->
<value>
<integer>%1</integer>
</value>
</parameter>
</methodParameters>
where:
%1 is a parameter named “numberOfSegments”. This is a int, and the value should conform to the following constraint: The value should be a strictly positive integer.. More formally, the constraint is:
%1 > 0
The default value is 1.
A list of criteria. Criteria can be activated or desactivated via the <active> tag (true or false). By default (no <active> tag), criteria are considered as active.
The input value should be a valid XMCDA document whose main tag is <criteria>. It must have the following form:
<criteria>
<criterion>
<active>[...]</active>
[...]
</criterion>
[...]
</criteria>
A list of alternatives. Alternatives can be activated or desactivated via the <active> tag (true or false). By default (no <active> tag), alternatives are considered as active.
The input value should be a valid XMCDA document whose main tag is <alternatives>. It must have the following form:
<alternatives>
<alternative>
<active>[...]</active>
[...]
</alternative>
[...]
</alternatives>
A performance table. The evaluations should be numeric values, i.e. <real>, <integer> or <rational>.
The input value should be a valid XMCDA document whose main tag is <performanceTable>.
The ranking of the alternatives, the best alternative having the lowest rank.
The input value should be a valid XMCDA document whose main tag is <alternativesValues>.
A list of messages generated by the algorithm.
The returned value is a XMCDA document whose main tag is <methodMessages>.
The value functions of the selected criteria.
The returned value is a XMCDA document whose main tag is <criteria>. It has the following form:
<criteria mcdaConcept="valueFunctions">
<criterion>
<criterionID>[..]</criterionID>
<criterionFunction>
<points>
<point>
<abscissa><real>[...]</real></abscissa>
<ordinate><real>[...]</real></ordinate>
</point>
</points>
</criterionFunction>
</criterion>
</criteria>
