I read the information in the link above to learn more about the Progress reports: interpreting the node log. However, there is an 'integral' word present in the 'objective' column, and I'm not sure how to interpret it and why it is there. Could any provide the answer? All answers would be appreciated!

Hi,
My understanding is that the cplex log will report integral when it founds an integral solution for the MIP, and that the objective for this solution is found in the best integer column.
In docplex, there is no such report as you can check the integrality of objective by code.
Note: Questions specifc to CPLEX are best asked on the support forum: https://www.ibm.com/mysupport/s/forumsproduct?language=en_US&name=ILOG%20CPLEX%20Optimization%20Studio&id=0TO50000000226IGAQ
Best regards,
Dear vlkong,
