Public Member Functions

procedure, public init => migrate_init_zero
 Initialise the migrate behaviour component to a zero state. See the_behaviour::migrate_init_zero(). More...
 
procedure, public do_this => migrate_do_this
 The "do" procedure component of the behaviour element performs the behaviour without affecting the actor agent (the_agent) and the world (here food_item_eaten) which have intent(in), so it only can change the internal representation of the behaviour (the type to which this procedure is bound to, here MIGRATE). See the_behaviour::migrate_do_this(). More...
 
procedure, public expectancies_calculate => migrate_motivations_expect
 the_behaviour::migrate::expectancies_calculate() (re)calculates motivations from fake expected perceptions following from the procedure migrate::do_this() => the_behaviour::migrate_do_this(). See the_behaviour::migrate_motivations_expect(). More...
 
procedure, public execute => migrate_do_execute
 Execute this behaviour component "migrate" by this_agent agent. See the_behaviour::migrate_do_execute(). More...
 
- Public Member Functions inherited from the_behaviour::move
procedure(move_init_root), deferred, public init
 The the_behaviour::move::init() is a deferred function that is overriden by each extension object init method. More...
 
- Public Member Functions inherited from the_behaviour::behaviour_base
procedure(behaviour_init_root), deferred, public init
 Abstract init function that has to be overriden by each object that extends the root behaviour component class. More...
 
procedure, public is_executed => behaviour_root_get_is_executed
 Get the execution status of the behaviour unit. See the_behaviour::behaviour_root_get_is_executed(). More...
 
procedure, public gos_expected => behaviour_root_gos_expectation
 gos_expected is an accessor get-function that returns the final GOS expectation from expectancies_calculate. Once we get this value for all the possible behaviours, we choose what behaviour to execute by minimising gos_expected. See the_behaviour::behaviour_root_gos_expectation(). More...
 
procedure, public attention_transfer => behaviour_root_attention_weights_transfer
 attention_transfer transfers attention weights from the actor agent to this behaviour expectancy objects. See the_behaviour::behaviour_root_attention_weights_transfer(). More...
 

Public Attributes

type(spatialtarget_point
 Target point (with offset) for migration into the target environment. More...
 
real(srp) expected_cost_moving
 The body mass cost of movement; depends on the distance. More...
 
real(srp) expected_food_gain
 The expected food gain (for body mass increment). More...
 
real(srp) expected_food_dir
 The expected direct food perception in the novel target habitat. More...
 
integer 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. More...
 
real(srp) expected_pred_dir_risk
 The expected direct predation risk is zero for random walk. More...
 
real(srp) expected_predation_risk
 The expected general predation risk, i.e. the risk depending on the current number of predators in both the perception and memory stack. More...
 
- Public Attributes inherited from the_behaviour::move
real(srp) distance
 Movement is described by its absolute distance. More...
 
- Public Attributes inherited from the_behaviour::behaviour_base
logical is_active
 Logical flag indicating that this behaviour is activated (executed). More...
 
type(motivationexpectancy
 Each behavioural type within the whole repertoire has expectancies that set how each of the GOS motivational components is affected by its execution. More...
 
real(srp) arousal_expected
 An expectation of the arousal level. It is the maximum weighted value among all motivation components. This value is actually minimised – those behaviour which would result in the lowest arousal_expected is finally executed. More...

Member Function/Subroutine Documentation

◆ init()

procedure, public the_behaviour::migrate::init

Initialise the migrate behaviour component to a zero state. See the_behaviour::migrate_init_zero().

Definition at line 375 of file m_behav.f90.

◆ do_this()

procedure, public the_behaviour::migrate::do_this

The "do" procedure component of the behaviour element performs the behaviour without affecting the actor agent (the_agent) and the world (here food_item_eaten) which have intent(in), so it only can change the internal representation of the behaviour (the type to which this procedure is bound to, here MIGRATE). See the_behaviour::migrate_do_this().

Definition at line 382 of file m_behav.f90.

◆ expectancies_calculate()

procedure, public the_behaviour::migrate::expectancies_calculate

the_behaviour::migrate::expectancies_calculate() (re)calculates motivations from fake expected perceptions following from the procedure migrate::do_this() => the_behaviour::migrate_do_this(). See the_behaviour::migrate_motivations_expect().

Definition at line 387 of file m_behav.f90.

◆ execute()

procedure, public the_behaviour::migrate::execute

Execute this behaviour component "migrate" by this_agent agent. See the_behaviour::migrate_do_execute().

Definition at line 390 of file m_behav.f90.
