  Memorylessness - Wikipedia, the free encyclopedia
For example, suppose a die is thrown as many times as it takes to get a "1", so that the probability of "success" on each trial is 1/6, and the random variable X is the number of times the die must be thrown.
To summarize: "memorylessness" of the probability distribution of the number of trials X until the first success means
the only probability distributions that enjoy (continuous) memorylessness are the exponential distributions.

The average size is still 707, which means that if you count the amount you're not paying, the total size is 1207.
Memorylessness means that the conditional distribution is the same as the unconditional distribution.
The distribution of the claim size minus 500, given that the claim is over 500, is the same as the distribution of the total claim size with no condition.

 Riding the Meridian -- Three-Dimensional Dementia 2 by Carolyn Guertin
The aesthetics of forgetting are found ideally in the freedom from past cares: a kind of liberation from history or a rebirth into living in an embodied state in the present moment.
Memorylessness could mark a return to innocence, to a preverbal state, or to the immersive environment of an eternal present.
But Violet is outside of time with her difficulties in communicating in the here and now.

 Synthstuff - music, photography and more...: Bill Whittle and the Lotus Eaters
A Brown University computer science paper defines memoryless behavior as a class of policies where “action decisions are made solely on this basis of the agent's current sensation.” On the face of it, “it would seem that memoryless behavior makes little sense.
It is the property of arriving at the same state however you started out, so that the current condition gives no clue as to how things were in the beginning.
I mention this because one of the historical goals of socialism was to precisely to create this memoryless state.

 Exponential distribution - Article from FactBug.org - the fast Wikipedia mirror site
An important property of the exponential distribution is that it is memoryless.
The exponential distributions are the only continuous memoryless probability distributions.
Because of the memoryless property of this distribution, it is well-suited to model the constant hazard rate portion of the bathtub curve used in reliability theory.

The M stands for Memorylessness which means a Poisson arrival process.
The M again stands for memoryless which means that the service times follow an exponential distribution.
Note that these probabilities are available for all models which have exponential (memoryless) service times.

In other words, if the device is alive at age t, the distribution of the remaining amount of time that it survives is the same as the original lifetime distribution (that is, it is as if the instrument does not remember that it has already been in use for a time t).
This is called the memorylessness property of the exponential distribution.
For the exponential distribution, because of the memorylessness property, it follows that the distribution of remailing life for a t-year old item is the same as for a new item.

We show that Safra's determinization of omega-automata with Streett (strong fairness) acceptance condition also gives memoryless winning strategies in infinite games, for the player whose acceptance condition is the complement of the Streett condition.
Both determinization and memorylessness are essential parts of known proofs of Rabin's tree automata complementation lemma.
Also, from Safra's determinization construction, along with its memoryless winning strategy extension, a single exponential construction and proof first appeared in [N. Klarlund (1992), Progress measures, immediate determinacy, and a subset construction for tree automata, in ``Proceedings, 7th IEEE Symposium on Logics in Computer Science''].

 Carlos Magana, "College Textbooks and the Holocaust, 1952-1978"
For if they are not recorded in history, the events of the past vanish into memorylessness, irretrievably lost to the present and the future.
This quotation is particularly important when discussing the textbooks from the fifties which omit accounts of events from their pages.
However, the Holocaust will not be an event that will vanish into 'memorylessness.' As I hope that this research has shown, authors of textbooks in the 1960s, more specifically after 1964, begin to present the Holocaust in its proper place in history.

 An R&D Race with Knowledge Accumulation
I develop a model of an R&D race with knowledge accumulation.
My model does not inherit the memorylessness property of the exponential distribution that troubles existing models of R&D races.
Hence, firms' knowledge stocks are no longer irrelevant to their behavior during the R&D race, and knowledge accumulation has strategic implications.

This need has spawned an industry of software search engines, all of which are based on indexing the content of Web nodes (pages) by key words and key phrases.
One fundamental problem of current search technologies is memorylessness.
Every search is launched afresh with no mechanism for systematic and formalized information sharing among similar searches.

And we over 35 also seem to recall the relationship of the color RED and a crescent like shape to that enemy now part of the “memorylessness” (Wretchard’s word) of the Left Stream Media:
THE USSR - OFF THE MAP - OUT OF HISTORY.
Lefty Architect use of color red for blood and fire is quite sensitive.
