Damerau & Levenshtein distance, 1964:
An extension of Levenshtein distance; In addition to Levenshtein distance, additional recurrence has been computed, a.k.a. transposition, and calculated as:
{TRUE}
if ( i > 1 AND j > 1 AND string[ i ] = string [ j  1 ] AND string[ i  1 ] = string [ j ] ) then
2d_array [ i, j ] := is going to be assigned min (
2d_array [ i, j ],
2d_array [ i  2, j  2 ] + cost
)
Damerau & Levenshtein distance is a.k.a. edit distance. Can be used in natural language processing; Cannot be used in Metric tree;
/****/
Damerau & Levenshtein distance between string and string can be written as:

For i from 0 to length_of_string

For j from 0 to length_of_string
2d_array [ 0, j ] := is going to be assigned j

If string[ i ] = string[ j ] then

Fuzzy distance, Foundations of Soft CaseBased 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 Euclidean distances 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} ( 1 〱= j 〱= n ),
Weight W_{journey} ( W_{journey} Є [ O, 1] );
Weighted distance:
Wd_{AȢ} = Wd ( Ed_{1}_{A}, Ed_{1}_{Ȣ} ) = [ _{journey = 1}Σ^{n} W^{2}_{journey} (X_{Ajourney}  XȢ_{journey})^{2} ]^{1/2}
a.k.a. ( _{journey = 1}Σ^{n} W^{2}_{journey} X^{2}_{journey })^{1/2} ;
WHERE X^{2}_{journey }= (X_{Ajourney}  XȢ_{journey})^{2;}
Weighted Similarity Measurement:
WSM_{AȢ} = 1 / ( 1 + positive constant カ Weighted distance Wd_{AȢ} );
Mapping 〱Fuzzy_{journey} X Fuzzy_{journey} 〉[ O, infinity ],
WHERE point p_{journey} of distance follows:
point p_{journey} ( A, Ȣ) = O IFF A = Ȣ;Also see: 2point distance
point p_{journey} ( A, Ȣ ) = point p_{journey} ( Ȣ, A );
point p_{journey} ( A, Ȣ ) 〱= less than or equal to point p_{journey} ( A, C ) + point p_{journey} ( C, Ȣ );npoint
IFF A AND Ȣ are real numbers,
point p_{journey} ( A, Ȣ ) =  A  Ȣ ;
IFF string AND string are intervals,
point p_{journey} ( string, string ) = max_{AЄstring, ȢЄstring}  A  Ȣ ;
{  1  if A ≠ Ȣ  
IFF A AND Ȣ are symbols,  point p_{journey} ( A, Ȣ ) =  
O  if A = Ȣ 
Thus weighted fuzzy distance:
= カsquare root of √ ( _{ journey = 1}Σ^{n} W^{2}_{journey } point p^{2}_{journey} ( Ed_{1}_{A}, Ed_{1}_{Ȣ} ) );

Jaro & Winkler distance, 1999:

Length of common prefixes l with prefix constant scale factor p prompt Jaro & Winkler distance for string and string can be calculated with weighted as:
d_{w} = d_{j }+ ( l * p * (1  d_{j} ))
