+## Criteria for the evolvability of linear deformations
 
+### Variability
 
-## Evolvierbarkeitskriterien
+In \cite{anrichterEvol} variability is defined as
+$$V(\vec{U}) := \frac{\textrm{rank}(\vec{U})}{n},$$
+whereby $\vec{U}$ is the $m \times n$ deformation-Matrix used to map the $m$
+control points onto the $n$ vertices.
 
-- Konditionszahl etc.
+Given $n = m$, an identical number of control-points and vertices, this
+quotient will be $=1$ if all control points are independent of each other and
+the solution is to trivially move every control-point onto a target-point.
 
-# Hauptteil
+In praxis the value of $V(\vec{U})$ is typically $\ll 1$, because as
+there are only few control-points for many vertices, so $m \ll n$.
+
+Additionally in our setup we connect neighbouring control-points in a grid so
+each control point is not independent, but typically depends on $4^d$
+control-points for an $d$-dimensional control mesh.
+
+### Regularity
+
+Regularity is defined\cite{anrichterEvol} as
+$$R(\vec{U}) := \frac{1}{\kappa(\vec{U})} = \frac{\sigma_{min}}{\sigma_{max}}$$
+where $\sigma_{min}$ and $\sigma_{max}$ are the smallest and greatest right singular
+value of the deformation-matrix $\vec{U}$.
+
+As we deform the given Object only based on the parameters as $\vec{p} \mapsto
+f(\vec{x} + \vec{U}\vec{p})$ this makes sure that $\|\vec{Up}\| \propto
+\|\vec{p}\|$ when $\kappa(\vec{U}) \approx 1$. The inversion of $\kappa(\vec{U})$
+is only performed to map the criterion-range to $[0..1]$, whereas $1$ is the
+optimal value and $0$ is the worst value.
+
+This criterion should be characteristic for numeric stability on the on
+hand\cite[chapter 2.7]{golub2012matrix} and for convergence speed of evolutional
+algorithms on the other hand\cite{anrichterEvol} as it is tied to the notion of
+locality\cite{weise2012evolutionary,thorhauer2014locality}.
+
+### Improvement Potential
+
+In contrast to the general nature of variability and regularity, which are
+agnostic of the fitness-function at hand the third criterion should reflect a
+notion of potential.
+
+As during optimization some kind of gradient $g$ is available to suggest a
+direction worth pursuing we use this to guess how much change can be achieved in
+the given direction.
+
+The definition for an improvement potential $P$ is\cite{anrichterEvol}:
+$$
+P(\vec{U}) := 1 - \|(\vec{1} - \vec{UU}^+)\vec(G)\|^2_F
+$$
+given some approximate $n \times d$ fitness-gradient $\vec{G}$, normalized to
+$\|\vec{G}\|_F = 1$, whereby $\|\cdot\|_F$ denotes the Frobenius-Norm.
