Comparison of terms related to agency

Term	Opposite
Agent
Optimizer, optimization process
consequentialist
expected utility maximizer
goal-directed, goal-based	act-based?
pseudoconsequentialist
mesa-optimizer

parameters to check for:

is it searching through a list of potential answers?
does it have an explicit model of the world? i.e. it has counterfactuals (see drescher on subactivation)
can it be modeled as having a utility function?
can it be modeled as having a utility function and selecting an action that does an argmax over actions? (note: this does not say how the argmax is implemented, which might be via a search or via some other more "control"-like process)
can we take an intentional stance toward it? i.e., is it useful (so far as predicting what it will do is concerned) to model it as having intentions?
is it solving some sort of optimization problem? (but what counts as an optimization problem?)
origin: was it itself produced by some sort of optimization process?
- eliezer's GLUT idea of "trace the improbability"
does it hit a small target, out of a large space of possibilities?
how many elements in the space of possibilities is it instantiating?
cost of evaluation of options/how good of a feedback we get for potential outputs
online vs offline (maybe also one-shot vs continually outputting things)
how well does it continue working when the environment/input changes?
cross-domain optimization power
coherence (if it makes sense to assign preferences)
does it pursue omohundro's "basic AI drives"? (i.e. it is the subject of instrumental convergence)
this post lists more formalizations for what "goal-directed" means

examples to check against:

humans
"subagents" inside of humans
human who is modeled inside the mind of another human (e.g. for the purposes of predicting behavior)
evolution/natural selection
bottlecap
RL system playing Pong without an explicit model
tool AGI/CAIS
task AGI
KANSI
mindblind AI
targeting system on a rocket
single-step filter
chess-playing algorithm that just does tree search (e.g. alpha-beta pruning algorithm)
a simple feed-forward neural network (e.g. one that recognizes MNIST digits)
a thermostat
a plant
multi-armed bandit problem
Solomonoff induction (outer layer/top-level reasoning)
plagiarizing robot
a system trained using imitation learning to behave similarly to another agent [1]
an agent that always twitches; see jessica's comment here
