kangaroo calculate random both tame and wild right?
tame is multiplied with a random number with G
wild is multiplied by ADD PUBKEY(target) with a random number
if both results is the same X that is collision right?
How can control range random of tame?
How can control range random of the wild?
control on Kangaroo 2.2 (use GPU)
(in python kangaroo script I can modify it)

distinguished point (DP)
-d: Specify the number of leading zeros for the DP method (default is auto)
-d dpBit
What mean if use -d ?
-d 32 = distinguished point 32 bit
-d 64 = distinguished point 64 bit
-d 128 = distinguished point 128 bit
(I did not yet understand it)

Code:

kangaroo calculate random both tame and wild right?

It assigns a random starting point (basically a private key value) within the user defined start and end range; after that, the kangaroos jump forward/positive based on average jump size; usually range width / 2 + 1.

Code:

tame is multiplied with a random number with G

tame is calculating the point/key it landed on and generating the corresponding pubkey

Code:

wild is multiplied by ADD PUBKEY(target) with a random number

wild is calculating the point/key it landed on and generating the corresponding pubkey AND now adds the target pubkey

Code:

if both results is the same X that is collision right?

yes

Code:

What mean if use -d ?
-d 32 = distinguished point 32 bit

to keep it easy to understand, each character in the pubkey is equal to 4 bits. Each pubkey has 64 characters times 4 bits = 256 bits
so for a dp of 32, the pubkey has to start with 8 zeros (leading zeros); 8 x 4 = 32. for dp 28, 7 leading zeros, for dp 64, 16 leading zeros, etc.
