subtraction

j∗=arg⁡max⁡j(Fj−λlLj−λrRj−λsSj−λhHj),j^*=\arg\max_j\left( F_j-\lambda_l L_j-\lambda_r R_j-\lambda_s S_j-\lambda_h H_j \right),
subtraction

What this part means

Subtract the following term or group from the preceding one. A leading minus marks a negative quantity.

Its job in the formula

Subtract the following term or group from the preceding one. A leading minus marks a negative quantity.

The passage around this formula

The selection problem can be represented as j∗=arg⁡max⁡j(Fj−λlLj−λrRj−λsSj−λhHj)j^*=\arg\max_j\left( F_j-\lambda_l L_j-\lambda_r R_j-\lambda_s S_j-\lambda_h H_j \right). where FjF_j is task fit, LjL_j latency, RjR_j reproducibility risk, SjS_j security exposure, and HjH_j human coordination cost for surface j . The coefficients depend on the repository and consequence of error. There is no globally best surface.
