Why is the status of artificial life software so under-developed?

I don’t know for certain, but I can make a guess. This is just my opinion, some others may disagree. The field of ALife has four branches that I’m aware of: Self-Organizing/self assembly behavior. ...

Is artificial life really life or not?

"Life" is a definition humans use to classify objects according to the types of behavior humans perceive as unique to living creatures. Scientists and philosophers tend to define something ...

Is artificial life really life or not?

If you read Steven Levy's book, Artificial Life,you will find, as I did, the distinction between biological and "artificial" life blurred. If you think about it, what exactly is "life", anyway? A ...

Is it possible to perform neuroevolution without a fitness function?

You do not always need an explictly coded fitness function to perform genetic algorithm searches. The more general need is for a selection process that favours individuals that perform better at the ...

Can we use the Tierra approach to optimize machine code?

Yes it has been tried. In fact there is a whole field, dubbed Genetic Programming. There is an annual competition to obtain "Human-Competitive" algorithms, and many instances of those have been found ...

Is artificial life really life or not?

I like to take an "animist" approach. (It has been suggested to me that part of the reason Japanese designs are so effective is because of the cultural affinity for the concept per the Shinto ...

Has the spontaneous emergence of replicators been modeled in Artificial Life?

Although difficult to prove a negative, I don't think that this has been done. The most advanced simulations of low-level features are not capable of scaling to simulate large enough populations at ...

Is artificial life really life or not?

Wikipedia describes life as a characteristic of "physical entities having biological processes". The same source also describes a simulation as "the imitation of the operation of a real-world process ...

Is it possible that the fittest individuals in an Artificial Life population may be successful by not actively pursuing the rules of the environment?

It is entirely possible! You see, the agents will perform whatever actions are available to them, and if the evolutionary algorithm is setup correctly, whatever set of actions provides them with a ...

Is it possible to perform neuroevolution without a fitness function?

How can you assess the quality of any solution without a measure of quality, which, in the context of genetic algorithms, is known as fitness function? The term fitness function is due to the well-...

Has the spontaneous emergence of replicators been modeled in Artificial Life?

It's yes in cellular automata space, you have this old one from 1997: "Emergence of self-replicating structures in a cellular automata space" http://fab.cba.mit.edu/classes/S62.12/docs/...

Is artificial life really life or not?

Imho, it is life. Example: consider the possibility that we synthesized from completethe DNA of a human being, with zero atoms from another human, and grew said human in a lab. Most (and myself) ...

Is artificial life really life or not?

It wouldn't be considered alive if it doesn't have vital functions, such as nutrition, relation with the environment, and reproduction. While the first is easy (use a battery) and the second is the ...
