Far his wanderings once bore him,
Bore this aged, genial searcher;
One who listening sat before him
Much could learn from time to time.
"Johan Ludvig Heiberg 1860" by Bjornstjerne Bjornson

Guarded by the nine big moons?

In science:

We consider a minimal model of persistent random searcher with short range memory.
Optimizing persistent random searches
We calculate exactly for such searcher the mean first-passage time to a target in a bounded domain and find that it admits a non trivial minimum as function of the persistence length.
Optimizing persistent random searches
The random search problem addresses the question of determining the time it takes a searcher performing a random walk to find a target .
Optimizing persistent random searches
From the theoretical point of view, the search time can be quantified as the first-passage time of the random searcher to the target .
Optimizing persistent random searches
At larger scales however, most examples of searchers – even if random – have at least short range memory skills and show persistent motions, as is the case for bacteria or larger organisms, which cannot be described as Markovian scale invariant processes.
Optimizing persistent random searches
FIG. 1: (Color online) Example of search tra jectory for a persistent random searcher in a bounded domain.
Optimizing persistent random searches
XTargetStart~lp sistent random searcher – called persistent random walk model hereafter – with short range memory characterized by an exponential distribution of the length of its successive ballistic excursions P (l) ∝ l→∞ e−αl/lp, where lp is the persistence length of the walk and α a numerical factor.
Optimizing persistent random searches
MFPT to the target averaged over all possible starting positions and velocities of the searcher, and analyze its dependence on the persistence length lp (or equivalently ) and the volume X d .
Optimizing persistent random searches
While the position process alone is non Markovian, the joint process of the position and velocity of the searcher is Markovian.
Optimizing persistent random searches
This exact expression of the search time for a non Markovian searcher constitutes the central result of this paper.
Optimizing persistent random searches
Note that the search time diverges for lp → ∞ (or  → 1) because the searcher can then be trapped in extremely long unsuccessful ballistic excursions.
Optimizing persistent random searches
This defines the optimal strategy for a persistent random searcher, which is realized when the persistence length has the same order of magnitude as the typical system size.
Optimizing persistent random searches
Taking lp too large however becomes unfavorable since the searcher can be trapped in extremely long unsuccessful ballistic excursions, so that one indeed expects an optimum in the regime lp ∼ X .
Optimizing persistent random searches
We add stemming function using porter stemmer algorithm to both the crawler and searcher classes.

From this last point of view, this conjecture may be considered as a global version for polynomial maps of the classical Local Inversion Theorem, which explains largely the fascination that this conjecture exerts on generations of searchers for more than half a century.
