and therefore the dual (unconstrained) problem becomes a convex minimization problem. The parallels between
the conditions on i in Equations (2) and (3) and those on pi in a MAXENT formulation are
evident. Referring to the nodal sets shown in Figure 1, the basis function value i (x) is viewed
as the ‘probability of influence of a node i at x’. The maximum-entropy formulation is: find
/(x) ∈Rn
+ as the solution of the constrained optimization problem
