Hungarian Algorithm:

Weighed matching (k_(n,n)= A[B, A Є B]), w[n, n])
1:for each i 2 [ n ]
2:  do u[ i ] A maxj w[ (i, j )]
3: v[ i ]A 0
4:while ( G_(u,v)) has no perfect matching
5: do X A minimum vertex cover of ( G_(u,v))   
6: A min u[ i ] + v[ j ] - w[ i, j ] : fi, jg2 (A n X Є (B n X))
7:for each I 2 A nX
8: do u[ i ] A u[ i ] –“
9:For each I 2 B \ X
10: do v[ i ] A v[ i ] +
11:return perfect matching of ( G_(u,v))


Example 


Three workers to do Three task at the same time. Apply the Hungarian algorithm the cost matrix is,




TASK_A
TASK_B
TASK_C
WORKER_1
250
450
350
WORKER_2
400
400
350
WORKER_3
200
500
250


Solution:

STEP 1: 

Identify minimum in each row (show in ‘green’)



TASK_A
TASK_B
TASK_C
ROW_MINS
WORKER_1
250
450
350
250
WORKER_2
400
400
350

350
WORKER_3
200

500
250
200


Substract row mins from each element in their respective rows:



TASK_A
TASK_B
TASK_C
WORKER_1
0
200
100
WORKER_2
50
50
0
WORKER_3
200
300
50
COL_MINS
0
50
0

Identify minimum in each column (show in ‘green’).

Substract column mins from each element from their respective columns:



TASK_A
TASK_B
TASK_C
WORKER_1
0
150
100
WORKER_2
50
0
0
WORKER_3
0
250
50


This is reduced cost matrix.


STEP 2: 

Find the minimum no of horizontal and vertical lines to cover all 0’s:



TASK_A
TASK_B
TASK_C
WORKER_1
0
150
100
WORKER_2
50
0
0
WORKER_3
0
250
50

Since < 3 lines suffice, continue to step2.

Identify min of uncovered elements: uncovered min = 50


Substract min of uncovered matrix elements from the uncovered rows:



TASK_A
TASK_B
TASK_C
WORKER_1
-50
150
100
WORKER_2
50
0
0
WORKER_3
-50
250
50


Add the min of the uncovered matrix elements to the covered columns:



TASK_A
TASK_B
TASK_C
WORKER_1
0
100
50
WORKER_2
100
0
0
WORKER_3
0
200
0


STEP 3:

Find the minimum number of horizontal and vertical lines to cover all 0’s:



TASK_A
TASK_B
TASK_C
WORKER_1
0
100
50
WORKER_2
100
0
0
WORKER_3
0
200
0

Since it takes 3 linkes to cover all zero’s, STOP: an assignment is possible.


Construct a valid assignment of row to column labels using only matrix zeros:



TASK_A
TASK_B
TASK_C
WORKER_1
0
100
50
WORKER_2
100
0
0
WORKER_3
0
200
0


  1. Worker_1 can only be assigned to task_A.
  2. Worker_3 can only be assigned to task_C.
  3. Worker_2 can only be assigned to task_B.
