Computes ACUTA method - analytic center for UTA - which provides a set of additive value functions that have a central position in the polyhedron of admissible value functions, given some preference information (preference relation).

(For outputs, see below)
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>
<criterionID>[...]</criterionID>
</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>
<alternativeID>[...]</alternativeID>
</alternative>
</alternatives>
Values of criteria for different alternatives. It must contains IDs of both criteria and alternatives previously described.
The input value should be a valid XMCDA document whose main tag is <performanceTable>.
It must have the following form:
<performanceTable>
<alternativePerformances>
<alternativeID>[...]</alternativeID>
<performance>
<criterionID>[...]</criterionID>
<value>
<real>[...]</real>
</value>
</performance>
</alternativePerformances>
</performanceTable>
Optimization direction for the selected criteria (min or max).
The input value should be a valid XMCDA document whose main tag is <criteriaValues>.
It must have the following form:
<criteriaValues>
<criterionValue>
<criterionID>[...]</criterionID>
<value>
<label>[...]</label>
</value>
</criterionValue>
</criteriaValues>
Number of segments in each value function to be constructed by UTA.
The input value should be a valid XMCDA document whose main tag is <criteriaValues>.
It must have the following form:
<criteriaValues>
<criterionValue>
<criterionID>[...]</criterionID>
<value>
<integer>[...]</integer>
</value>
</criterionValue>
</criteriaValues>
Ranking (preorder) of alternatives, corresponding to pariwize preference and indifference statements.
The input value should be a valid XMCDA document whose main tag is <alternativesValues>.
It must have the following form:
<alternativesValues>
<alternativeValue>
<alternativeID>[...]</alternativeID>
<value>
<integer>[...]</integer>
</value>
</alternativeValue>
</alternativesValues>
Asymmetric part of the preference relation, representing strict preference statements, under the form of paiwise comparisons of alternatives.
The input value should be a valid XMCDA document whose main tag is <alternativesValues>.
It must have the following form:
<alternativesComparisons>
<pairs>
<pair>
<initial>
<alternativeID>[...]</alternativeID>
</initial>
<terminal>
<alternativeID>[...]</alternativeID>
</terminal>
</pair>
[...]
</pairs>
</alternativesComparisons>
Symmetric part of the preference relation, representing indifference statements, under the form of paiwise comparisons of alternatives.
The input value should be a valid XMCDA document whose main tag is <alternativesValues>.
It must have the following form:
<alternativesComparisons>
<pairs>
<pair>
<initial>
<alternativeID>[...]</alternativeID>
</initial>
<terminal>
<alternativeID>[...]</alternativeID>
</terminal>
</pair>
[...]
</pairs>
</alternativesComparisons>
Optional delta value for UTA - delta is the utility gap between two successive alternatives in the preference ranking.
The input value should be a valid XMCDA document whose main tag is <methodParameters>.
It must have the following form:
<methodParameters>
<parameter>
<value>
<real>%1</real>
</value>
</parameter>
</methodParameters>
where:
%1 is a parameter named “delta”. This is a float, and the value should conform to the following constraint: Delta should be positive and small . More formally, the constraint is:
%1 > 0 && %1 < 1
Constructed value functions for the selected criteria and the provided rankings, using ACUTA method.
The returned value is a XMCDA document whose main tag is <criteria>.
It has the following form:
<criteria mcdaConcept="criteria">
<criterion>
<criterionID>[...]</criterionID>
<criterionFunction>
<points>
<point>
<abscissa><real>[...]</real></abscissa>
<ordinate><real>[...]</real></ordinate>
</point>
</points>
</criterionFunction>
</criterion>
</criteria>
Log message.
The returned value is a XMCDA document whose main tag is <methodMessages>.
It has the following form:
<methodMessages mcdaConcept="methodMessage">
<logMessage>
<text>[...]</text>
</logMessage>
<errorMessage>
<text>[...]</text>
</errorMessage>
</methodMessages>
