Notation

As a math parser is currently not used, we write the math equations as formated text:

• Scalars are written as small italic letters, e.g. f
• Vectors are written as small bold letters, e.g. x.
• Matrices are written in capital bold letters, e.g. C.

Symbols

f, f	objective function(s)
x, x	design variable(s)
g, g	constraint(s)

Terminology

solution	The term solution is used in optimization. One solution (x,f,g,a) consists of a vector of design variables x, the evaluated objective(s) f(x), constraint(s) g(x), and optionally of additional values a.
design variables	The vector of design variables x may consist of real numbers (continuous variables), integers (discrete variables) or both (mixed variables).
