33 This mono-objective optimization algorithm allows to estimate the conditional
34 quantiles of the state parameters distribution, expressed with a model of the
35 observed variables. These are then the quantiles on the observed variables
36 which will allow to determine the model parameters that satisfy to the
37 quantiles conditions.

71   *List of names*. This list indicates the names of the supplementary
72   variables, that can be available during or at the end of the algorithm, if
73   they are initially required by the user. Their availability involves,
74   potentially, costly calculations or memory consumptions. The default is then
75   a void list, none of these variables being calculated and stored by default
76   (excepted the unconditional variables). The possible names are in the
77   following list (the detailed description of each named variable is given in
78   the following part of this specific algorithmic documentation, in the
79   sub-section "*Information and variables available at the end of the
80   algorithm*"): [

99 *Tips for this algorithm:*
100
101     As the *"BackgroundError"* and *"ObservationError"* commands are required
102     for ALL the calculation algorithms in the interface, you have to provide a
103     value, even if these commands are not required for this algorithm, and will
104     not be used. The simplest way is to give "1" as a STRING for both.
