Member Function/Subroutine Documentation

init()

procedure, public the_behaviour::go_up_depth::init

Initialise the go up to a shallower spatial layer behaviour component to a zero state. See the_behaviour::go_up_depth_init_zero().

Definition at line 454 of file m_behav.f90.

do_this()

procedure, public the_behaviour::go_up_depth::do_this

do_this performs the agent's action without changing the agent or the environment. See the_behaviour::go_up_do_this().

Definition at line 458 of file m_behav.f90.

expectancies_calculate()

procedure, public the_behaviour::go_up_depth::expectancies_calculate

expectancies_calculate is a subroutine (re)calculating motivations from fake expected perceptions following from do_this.

Note

Note that this is the computational engine to assess the expected GOS of the behaviour, it is called from within the base root behaviour class-bound polymorphic gos_expect. See the_behaviour::go_up_motivations_expect().

Definition at line 465 of file m_behav.f90.

execute()

procedure, public the_behaviour::go_up_depth::execute

Execute this behaviour component "go up" by this_agent agent. See the_behaviour::go_up_do_execute().

Definition at line 468 of file m_behav.f90.

Member Data Documentation

decrement_mass_cost

real(srp) the_behaviour::go_up_depth::decrement_mass_cost

The cost of the swimming downwards. Should be relatively low, much smaller than the cost of active locomotion to the same distance (in terms of the body length as set by condition_cost_swimming_burst()). This is because it is assumed to be based on the hydrodynamic (swimbladder) volume manipulation rather than active propulsion.

Definition at line 439 of file m_behav.f90.

expected_food_gain

real(srp) the_behaviour::go_up_depth::expected_food_gain

The expected food gain (body mass increment) from the food items deeper than the actor agent. This value is based on the number and average mass of food items below the agent's current horizon.

Definition at line 443 of file m_behav.f90.

expected_consp_number

integer the_behaviour::go_up_depth::expected_consp_number

The expected number of conspecifics at the layer below. This value is based on the number of conspecifics below the agent's current horizon.

Definition at line 446 of file m_behav.f90.

expected_predation_risk

real(srp) the_behaviour::go_up_depth::expected_predation_risk

The expected predation risk at the layer below. This value is based on the number of predators below the agent's current horizon.
