sudoku-determinant have been described well here : The Determinant Sudoku
I have created another one.
Number in the center is the value of the determinant
Numbers 0 to 10 are the values of the determinant
What's the solution for this sudoku?

2$\begingroup$ Are you sure this has a solution that can be found purely through logical deduction? I can't find a place to start. $\endgroup$– Deusovi ♦Oct 10, 2017 at 1:59

$\begingroup$ @Deusovi : Sorry, Not purely logical deduction. The puzzle need some computer calculation. $\endgroup$– Jamal SenjayaOct 10, 2017 at 3:53

$\begingroup$ @Jasen : No, it is 2. $\endgroup$– Jamal SenjayaOct 10, 2017 at 3:54

2$\begingroup$ That may be why people aren't starting the puzzle. It seems like writing a computer program to solve this would be the only way to do it, and that doesn't really make a fun puzzle. $\endgroup$– Deusovi ♦Oct 10, 2017 at 5:15

After a painful coding, I think the answer is :
[9,7,4 | 3,1,5 | 8,2,6]
[1,2,3 | 4,6,8 | 5,7,9]
[5,6,8 | 2,7,9 | 1,3,4]
-----------------------
[2,1,5 | 6,3,4 | 7,9,8]
[3,4,7 | 9,8,2 | 6,1,5]
[6,8,9 | 1,5,7 | 2,4,3]
-----------------------
[4,9,6 | 5,2,1 | 3,8,7]
[8,5,2 | 7,4,3 | 9,6,1]
[7,3,1 | 8,9,6 | 4,5,2]

Just to add to the existing answer the solution is actually not unique, there are exactly two (almost trivially similar) answers
In addition to Nurnani Tati's answer:
9 7 4 | 3 1 5 | 8 2 6 1 2 3 | 4 6 8 | 5 7 9 5 6 8 | 2 7 9 | 1 3 4 ------+-------+------ 2 1 5 | 6 3 4 | 7 9 8 3 4 7 | 9 8 2 | 6 1 5 6 8 9 | 1 5 7 | 2 4 3 ------+-------+------ 4 9 6 | 5 2 1 | 3 8 7 8 5 2 | 7 4 3 | 9 6 1 7 3 1 | 8 9 6 | 4 5 2
there is also
9 7 4 | 3 1 5 | 8 6 2 1 2 3 | 4 6 8 | 5 7 9 5 6 8 | 2 7 9 | 1 3 4 ------+-------+------ 2 1 5 | 6 3 4 | 7 9 8 3 4 7 | 9 8 2 | 6 5 1 6 8 9 | 1 5 7 | 2 4 3 ------+-------+------ 4 9 6 | 5 2 1 | 3 8 7 8 5 2 | 7 4 3 | 9 1 6 7 3 1 | 8 9 6 | 4 2 5
