Detailed Description
Radial attention model functional specification.
This file contains the declarations of the radial attention example of the article. It uses exponential specification for effort costs. If you want to change the specification you have to redefine the corresponding macros of this file and re-compile.
Function Documentation
◆ cost()
| double cost | ( | const struct objvar_st * | v | ) |
Attentional costs.
Calculates the attentional costs by
![\[ c(s,r') = (\mathrm{e}^{\alpha s} - 1)(1 - \gamma r'(s,r)). \]](form_5.png)
- Parameters
-
v Objective function data
- Returns
- Calculated costs.

◆ radt()
| double radt | ( | const struct objvar_st * | v | ) |
Radius transition.
Calculates the next date's radius by
![\[ r'(s,r) = 1 - (1 - \delta r) \mathrm{e}^{-s}. \]](form_3.png)
- Parameters
-
v Objective function data
- Returns
- Calculated next date's radius.
◆ util()
| double util | ( | const struct objvar_st * | v | ) |
Temporal utility.
Calculates the temporal utility by
![\[ u(q,r) = r'(s,r) (1 - \mathrm{e}^{-q}). \]](form_4.png)
- Parameters
-
v Objective function data
- Returns
- Calculated temporal utility.

◆ wltt()
| double wltt | ( | const struct objvar_st * | v | ) |
Wealth transition.
Calculates the next date's wealth
![\[ d(x,r') = R (x - r'(s,r) q). \]](form_6.png)
- Parameters
-
v Objective function data
- Returns
- Calculated costs.
