"We apply that higher average voltage to our circuit and gradually increase or decrease the voltage until all appropriate light bulbs of the circuit are turned on. Next, we measure the voltages of all appropriate branches of the circuit, and we compute any difference between assigned values and the measured values..."


Important Remark: We must sum all branch values (weights/voltages) after each applied voltage increase or decrease, generally, relative to the higher average voltage until the minimum (optimal) sum of all branch values (voltages) is achieved. Thus, we have confirmed that the optimal solution of TSP is achievable in polynomial time or less.

Moreover, minimize S (sum of all branch values (weights or voltages) for the undirected weighted graph or electrical circuit) subject to an increase or decrease or no change relative (generally) to the higher average value (voltage), [tex]H_{avg }[/tex], or more simply:

Minimize S relative to or at [tex]H_{avg }[/tex] where [tex]H_{avg }[/tex] is the average of all branch values... of our graph/circuit greater than the overall average branch value..., [tex]B_{avg }[/tex], where [tex]B_{avg }[/tex] = total sum of all branch values/weights/voltages of graph/circuit divided by the total number of branch values/weights/voltages for our graph/circuit.

Remark: Minimize S relative to or at [tex]H_{avg }[/tex]...

Thus, we have tentatively/briefly constructed a polynomial-time algorithm that solves TSP, optimally.

Math works! Thank Lord GOD! Amen! Go Blue! :D

Please disregard the last update/previous post since it is flawed!

Remark: Design/development/testing of algorithms is generally hard work. We must be careful to get right. Good Luck! :D

An Important Point of Clarity: We must apply the same voltage/value/weight (plus or minus or equal to [tex]H_{avg }[/tex]) to each branch of our graph/circuit until the optimal solution (minimum S) is achieved. And therefore, the total value/weight/load/voltage is more or less S for the graph/circuit. I apologize for any confusion or lack of clarity...

And therefore, formulating a polynomial-time algorithm is not an easy task because we decide what branch values need to change or remain the same. Good Luck! :D

Updated Remark: The minimum function, min(), helps us decide what branch values to keep or to ignore in our computations...

The use of the word, change, is inappropriate here and in some previous posts too.

TSP:

"Input: A complete, directed graph G with positive distances assigned to each edge (branch) in the graph.

Output: The shortest simple cycle that includes every vertex (node/city)."

We recall TSP (Traveling Salesman Problem).

TSP:

"Input: A complete, directed graph (digraph) G with positive distances assigned to each edge (branch) in the graph.

Output: The shortest simple cycle that includes every vertex (node/city).

Remark: Another possibility (correction) is to make a directional connection between node 0 and node 1. Please see diagram below.

Remark: We can write an algorithm that inputs a complete digraph (G) with any number of nodes (n), a number of directed edges (e), and with positive distances ([tex]d_{ij }[/tex]) between nodes, i and j.

What is the algorithm?
