Document Summary

Optimality theory tests ideas about function and adaptation. Decision: the choice point with set amount of outcomes. Strategy set: the range of possible abilities of the animals. Optimization criterion: the goal or purpose of the behaviour, eg. Constraints: variables that the foraging animal cannot control or do anything about. Optimization models for animal behaviour originated from engineers and businesses. Decision: what to build, what to eat. Strategy set: design, materials, time and choice. Optimization: cost, traffic (the bridge has to be able to support a certain number of vehicles), goals/purpose of the bridge, maximize rate. Constraints: length, height, materials, day length, handling time, memory. Energy content: aquatic (a, energy 3. 8 kcal/g, terrestrial (t, energy 4. 25 kcal/g. Energy constraint: 3. 8a + 4. 25t more or equal to 14000. Density: aquatic (a, 20ml/g, terrestrial (t, 4. 04 ml/g. Rumen capacity constraint: 20a + 4. 04 t less or equal to 32, 900. Sodium content: aquatic (a, 0. 003g na/g, terrestrial (t, 0g na/g.
