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

Why this formula appears here

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 explicitly makes the hidden step visible: the ranking that comes out depends entirely on λc\lambda_c and λl\lambda_l , numbers that are not properties of the agents at all. A call center with razor-thin per-ticket margins and a research lab doing one-off due-diligence work on a handful of contracts will set λc\lambda_c at wildly different values, and the two will…

Equation 18 · Model Evaluation

Why Cost and Latency Belong in the Evaluation Score, Not a Footnote

This equation states an equality: the expressions on both sides have the same value under the article’s assumptions.
