You have four tasks. Task 1 takes a maximum of 1 ms to execute and runs every 5 ms. Task 2 takes a maximum of 0.5 ms to execute and runs every 2 ms. Task 3 takes a maximum of 1 ms to execute and runs every 20 ms. Task 4 takes a maximum of 5 ms to execute and runs every 10 ms. Do you think a scheduling algorithm exists? Justify your answer.

These are the candidates:

Round Robin: Run the ready threads in circular fashion, giving each the same amount of time to execute. Rate Monotonic: Assign importance according to these periods with more frequent tasks having higher importance. Priority: Run the most important ready threads first, running less important threads only if there are no important threads ready. Cooporative: Threads themselves decide when to stop running. Exponential Queue: A dynamic scheduler that shifts importance depending on if the thread ran to the completion of its time slice.
