I have 4 optimization exercises that need to be solved. See exercises in the attached file.
I am ready to pay 10 Euro per earned point as given in the description - i.e. if you can solve all of them and that within 48 hours after awarding the project and with clear handwriting and drawings, you can earn 12 point, i.e. 120 Euro altogether. If awarded, I will create milestones for each exercise and only those will be paid (released) that are corretly solved within the time frame given.
I need the solutions with mathematically clear notations and clear handwriting.
