Detailed Description

A new function defined by the user in the VNNLIB language using the define-fun command.

In the VNNLIB language, a function definition is a way to define a function in terms of its parameters and body. A function defined in this way can be called with the operator() method by providing the required arguments.

// Example usage:
const Variable lhs{"lhs"}, rhs{"rhs"};
const FunctionDefinition fun_sum{{lhs_, rhs_}, Sort::Real, Term{lhs_ + rhs_}};
 
Term res = fun_sum(Term{5}, Term{6});
 
std::cout << res << std::endl;
// Output:
// 11
