Types ¶
type CacheFunction ¶
type CacheFunction interface {
Function
SetBase(function CacheFunction)
Cache() []CacheData
SetCache([]CacheData)
}
A CacheFunction represents a fitness function that caches data for efficiency.
func NewTrianglesImageFunction ¶
func NewTrianglesImageFunction(target image.Data, blockSize int) CacheFunction
NewTrianglesImageFunction returns a new fitness function.
func PolygonsImageFunctions ¶
func PolygonsImageFunctions(target image.Data, blockSize, n int) []CacheFunction
func TrianglesImageFunctions ¶
func TrianglesImageFunctions(target image.Data, blockSize, n int) []CacheFunction
TrianglesImageFunctions returns an array of fitness functions.
type Function ¶
type Function interface {
// Calculate evaluates a point group and returns a fitness.
Calculate(data PointsData) float64
}
A Function represents a fitness function to evaluate a point group.
type PointsData ¶
type PointsData struct {
Points normgeom.NormPointGroup
Mutations []mutation.Mutation
}
PointsData stores data regarding a point group, and is used by the fitness function.
type PolygonCacheData ¶
type PolygonCacheData struct {
// contains filtered or unexported fields
}
func (PolygonCacheData) CachedHash ¶
func (p PolygonCacheData) CachedHash() uint32
func (PolygonCacheData) Data ¶
func (p PolygonCacheData) Data() float64
func (PolygonCacheData) Equals ¶
func (p PolygonCacheData) Equals(other CacheData) bool
Equals returns if the TriangleCacheData is equal to another.
func (PolygonCacheData) Hash ¶
func (p PolygonCacheData) Hash() uint64
Hash calculates the hash code of a TriangleCacheData.
func (*PolygonCacheData) SetCachedHash ¶
func (p *PolygonCacheData) SetCachedHash(hash uint32)
type TriangleCacheData ¶
type TriangleCacheData struct {
// contains filtered or unexported fields
}
TriangleCacheData stores the triangles vertices and its fitness, and is used to cache calculations.
func (TriangleCacheData) CachedHash ¶
func (t TriangleCacheData) CachedHash() uint32
func (TriangleCacheData) Data ¶
func (t TriangleCacheData) Data() float64
func (TriangleCacheData) Equals ¶
func (t TriangleCacheData) Equals(other CacheData) bool
Equals returns if the TriangleCacheData is equal to another.
func (TriangleCacheData) Hash ¶
func (t TriangleCacheData) Hash() uint64
Hash calculates the hash code of a TriangleCacheData.
func (*TriangleCacheData) SetCachedHash ¶
func (t *TriangleCacheData) SetCachedHash(hash uint32)
