Discrepancy in Results Compared to Research Paper in Sun2020Distributed

[Zeinab-E]

I appreciate your valuable work in simulating papers.
I tried to try your code regarding Sun2020Distributed but the obtained results are different from the results in the paper. For example, the state trajectories of all agents are not converged to the optimal solution.
I would greatly appreciate it if you could clarify it.
The results from the paper are as follows:

the results obtained from your code are as follows:

You can see the discrepancy between results.
