Question

What is backtracking in algorithm design and analysis?

Answer 1

Here is your answer ⤵⤵⤵

Backtracking is a general algorithm for finding all (or some) solutions to some computational problems, notably constraint satisfaction problems, that incrementally builds candidates to the solutions, and abandons a candidate ("backtracks") as soon as it determines that the candidate cannot possibly be completed to a ...

Answer 2

If voltage is applied between terminals 1 and 2 when terminals 3 and 4 are open, the power liberated is p1 = 40 w and when terminals 3 and 4 are connected, the power liberated is p2 = 80 w. If the same source isc onnected to the terminals 3 and 4, the power liberated in the circuit when terminals 1 and 2 are open is p3 = 20 w. Determine the power p4 consumed in the circuit when the terminals 1 and 2 are connected and the same voltage is applied between the terminals 3 and 4.
