Set, Set Element and String Expressions

Several types of expressions

Expressions are organized arrangements of operators, constants, sets, indices, parameters, and variables that evaluate to either a set, a set element, a numerical value, a logical value, a string value, or a unit value. Expressions form the core of the AIMMS language. In the previous chapters you already have seen some elementary examples of expressions.

This chapter

In this chapter, set, set element and string expressions are presented in detail. For expressions that evaluate to either numerical or logical values, you are referred to Numerical and Logical Expressions. Expressions that evaluate to unit values are discussed in Unit Expressions
