Xpress-SP error codes


E-105   cannot aggregate these scenarios

Scenarios should have a common ancestral node

E-108   cannot load the matrix
E-109   expected value problem is infeasible

Expected Value problem with Recourse cannot be solved

E-110   illegal division by zero
E-111   invalid scenario tree
E-116   perfect information problem infeasible
E-117   probabilities for all the branches not set

Conditional probabilities at certain nodes are not set

E-118   probabilities not within tolerances
E-120   scenarios not generated yet
E-123   sprands in the first stage should take one value with probability 1.0

First stage stochastic random elements are deterministic

E-133   scenario tree does not exist
E-134   wrong scenario number entered
E-135   sprand does not exist
E-136   sprandexp does not exist
E-137   spvar does not exist
E-138   splinctr does not exist
E-139   node does not exist
E-140   global constraints can occur only in a recourse problem
E-141   cannot set the bound of spvar through (unnamed) splinctr

Unnamed constraints are assumed be bounds. A bound should be of the form xMaths/leq.pnga or xMaths/geq.pnga, where x is spvar and a is real, sprand or sprandexp

E-143   col / row not found in the matrix
E-145   cannot build scenarios
E-146   cannot evaluate at earlier stages

The value of the stochastic entity is realized at a later stage

E-148   problem type and entity attribute conflict

Entity must belong to 1st stage or an expected val prob or a problem at a node / in a scenario or be a global, and not fixed / hidden. A reference to scenario number or a node number is required

E-149   problem type and entity attribute conflict

Entity entity belongs to an expected value problem or a problem at a node / in a scenario, or is fixed / hidden / global. A reference to scenario number or a node number should not be provided

E-151   cannot have fixed variables in sos type constraints
E-152   sos should be unconstrained
E-153   invalid stage of stochastic bound for spvar

The stage number of stochastic bound should be Maths/leq.png that of stochastic variable

E-155   constraints or bounds pertaining to fixed variables are not satisfied

One or more constraints containing only fixed variables are being violated, givent the values of fixed variables

W-100   duplicate entry found
W-101   fixing variables and hiding constraints
W-102   hiding constraint, since all variables are fixed

If all variables in a constraint are fixed then the constraint is automatically hidden

W-103   ignoring invalid splinctr
W-104   scenarios already generated; generating again from scratch
W-105   setting negative lower bound of a non-free spvar
W-106   setting xsp_cond_prob to true because xsp_scen_based is false
W-107   sprands do not assume any realized values
W-108   sprands in the first stage cannot be random
W-109   stage already set
W-110   sense of constraint is unchanged
W-111   lower bound set to -inf
W-112   changing bounds
W-113   stage not set or invalid stage
W-114   ignoring unused spvar
W-107   If a variable does not participate in any constraint, it is automatically rejected
W-115   implicitly stages not set
W-116   special ordered sets used only in recourse, expected value or perfect information problems
