Detailed Description

Variable class contains methods for defining and changing variables of a Problem. A variable has bounds (lb, ub), a type (binary, integer, continuous), a name, and an id which is unique for the variable and is usually generated by the Problem.

getIndex()

UInt Minotaur::Variable::getIndex ( ) const

inline

Many operations rely on arrays of values. index_ is the index of variable in such arrays. Thus x[index_] will give the value of this variable in an array x, provided x was populated that way (Most engines etc. will populate it on the basis of index_).
