- Since we did not find an alternative slot for next week's lecture, we are skipping it.

- Please tell me if you would like to change the starting time of the lectures.

- The web page for the course is at https://wp.software.imdea.org/cbc/ I assume you all have programming experience. If you are not strong in logic, please have a look at the recommended material.

Best,

Manuel
