__ Damerau & Levenshtein distance,

An extension of Levenshtein distance; In addition to Levenshtein distance, additional recurrence has been computed, a.k.a. transposition, and calculated as:

2d_array [ i, j ] := is going to be assigned min (

Damerau & Levenshtein distance is a.k.a. edit distance. Can be used in natural language processing; Cannot be used in Metric tree;

/****/

If string[ i ] = string[ j ] then

__Fuzzy ____
distance, Foundations of Soft Case-Based
Reasoning, Pal & Shiu, 2004__:

WHERE corresponding objects "not subjects" in different coordinates, and those objects' locations can be represented as set of real numbers, and those sets are needed to be ordered [also see: Orbit] therefore must be weighted;

FuzzySVMs' traveling journeys
can be collected as {F_{journey}
(journey = 1, 2,
3, 4, 5,
6, ...) and notice that
journey 1, 2,
3, 4, 5, 6, ... n can become
N Euclidean distances;

Therefore N **E**uclidean **d**istances
can be represented as:

distance_without_weight = {
Ed_{1}, Ed_{2}, Ed_{3}, Ed_{4}, ... , Ed_{N }
};

For each Ed
i^{th}
, dimensional vector (n + 1) can be represented as:

Ed_{i} = (xyz_{i1}, xyz_{i2},
xyz_{i3}, xyz_{i4}, ... , xyz_{iN}, θ_{i});

WHERE xyz_{ij}
corresponds to fuzzy member functions of

F_{journey}
( 1 〱= j 〱= n ) AND
θ_{i }
corresponds 〉Dimensional Time.Space.Action's

action ( i = 1, 2, 3, 4, 5, 6, ... , N);

For each F_{journey}

a.k.a.
( _{journey = 1}Σ^{n} W^{2}_{journey}

WHERE X^{2}_{journey }= (X_{Ajourney}

WHERE **p**oint p_{journey}

**p**oint p_{journey} ( A, Ȣ) = O IFF A = Ȣ;Also
see:

**p**oint p_{journey} ( A, Ȣ ) = **p**oint p_{journey}

IFF A AND Ȣ are real numbers,

**p**oint p_{journey}
( A, Ȣ ) = | A - Ȣ |;

IFF string AND string are intervals,

**p**oint p_{journey} ( string,

IFF A AND Ȣ are symbols, | point p_{journey}

Thus weighted fuzzy distance:
