Constructive A type of interaction between a goal's active members where a high
Interaction utility for one member leads to a high overall utility for the goal.
Constructive interaction is modeled by a multiplicative MUF formula
where the sum of the weights (small ks) is more than 1.0, and the
interaction scaling constant big K is less than 0.0.

See Utility.
The certainty equivalent of a probabilistic level of a measure for an
alternative is the level for that measure that is equally preferred to the
uncertain outcome defined by the probability distribution.
LDW computes the certainty equivalent by finding the expected
utility (defined by summing (integrating) prob(x)U(x) for all levels x
whose probability is greater than 0) for the probability distribution.
The certainty equivalent is the level y such that U(y) equals the
expected utility for the probability distribution.

A default is a value for a variable assigned by LDW in the absence of
a specification from the user. Defaults include
! Measure Levels for Alternatives -- set to the most preferred
level for the measure.
! SUF curves -- set to straight lines over the measure's entire
range.
! Level types -- assumed to be point estimates rather than
probabilistic
! MUF scaling constants -- assumed that all active members of
a goal have equal weights (equal small ks in an
additive MUF)
