== Definitions ==
=== Absolute ===
Based on the absolute value of zeta(s), which is more mathematically convenient to calculate at σ = 0.5.
=== Real ===
Based on the real part of zeta(s), which directly follows from the [[The Riemann zeta function and tuning/Vector's derivation|derivation of zeta as an equal tuning badness metric]].
== Zero-based metrics ==
== Zero-based metrics ==
Zeta metrics corresponding to regions between zeros on the critical line (σ = 0.5). The Riemann hypothesis is the equivalent to the statement that regions between zeros correspond directly to peaks.  
Zeta metrics corresponding to regions between zeros on the critical line (σ = 0.5). The Riemann hypothesis is the equivalent to the statement that regions between zeros correspond directly to peaks.

< Riemann zeta function

Definitions

Absolute

Based on the absolute value of zeta(s), which is more mathematically convenient to calculate at σ = 0.5.

Real

Based on the real part of zeta(s), which directly follows from the derivation of zeta as an equal tuning badness metric.

Zero-based metrics

Zeta metrics corresponding to regions between zeros on the critical line (σ = 0.5). The Riemann hypothesis is the equivalent to the statement that regions between zeros correspond directly to peaks.
