More mutation operations?

[qianqianpang]

Respected researchers and developers
By reading your code, I found that the mutation stage implements mutation on ABI parameters, blockchain environment-related parameters, and state snapshots.

I would like to ask if you have implemented mutation operations on the functions (transaction sequence order) in the ABI structure.

Hi, state snapshots mutation is transaction sequence order mutation. For example:

Snapshot A: buy(1) => sell(1)
Snapshot B: buy(2) => sell(2)

Input 1: Buy Tx on Snapshot A: buy(1) => sell(1) => buy(2), which derives Snapshot C (buy(1) => sell(1) => buy(2))

Snapshot Mutations on Input 1 can be:

• Buy Tx on Snapshot B: buy(2) => sell(2) => buy(2)
• Buy Tx on Snapshot C: buy(1) => sell(1) => buy(2) => buy(2)
