Equation 18 · Part 2 · Why Cost and Latency Belong in the Evaluation Score, Not a Footnote

Symbol A

Uλ(A)=sA−λc cA−λl lA.U_{\lambda}(A) = s_A - \lambda_c\, c_A - \lambda_l\, l_A .

What this part means

the agent.

Its job in the formula

A is an argument of the function-like quantity on the left; its role is set by that function’s stated inputs.

Where the article explains it

Agent A and Agent B from the opening example are exactly such a pair: A wins on s , B wins on both c and l , and the Pareto relation is silent about which is “better.

The passage around this formula

Make that judgment explicit and it becomes a scalarized score. Choose exchange rates λc\lambda_c (accuracy points per dollar) and λl\lambda_l (accuracy points per second of latency), and define Uλ(A)=sA−λc cA−λl lAU_{\lambda}(A) = s_A - \lambda_c\, c_A - \lambda_l\, l_A . This is a legitimate way to rank agents, and it is what most procurement decisions ultimately have to do. But writing it out this…

A variable is a named place for a value. Its letter is a local label: x can mean position in one formula and a data point in another.
