34. systems/evolution

Part: V · Systems
Package: github.com/openfluke/welvet/systems/evolution
Status: ok — ✅

When

Adaptation, measurement, or evolution (systems/evolution).

Where

import "github.com/openfluke/welvet/systems/evolution"

cd 34-evolution && source ../env.sh && go run .

Why

Topology search and weight crossover need first-class splice + NEAT on CPU-resident grids.

What

SpliceDNA, NEATMutate, NewNEATPopulation, CloneGrid — dtype/quant preserved via SetFromF32.

Sample output (captured)

<nil>

Live capture from go run ./cmd/runall on local ../../welvet (exit 0).
