Abstract
The study of semifeasible algorithms was initiated by Selman's work a quarter of century ago [Sel79,Sel81,Sel82]. Informally put, this research stream studies the power of those sets
L
for which there is a deterministic (or in some cases, the function may belong to one of various nondeterministic function classes) polynomial-time function
f
such that when at least one of
x
and
y
belongs to
L
, then
f(x, y) ∈ L ∩ {x, y}
. The intuition here is that it is saying: "Regarding membership in
L
, if you put a gun to my head and forced me to bet on one of
x
or
y
as belonging to
L
, my money would be on
f(x, y)
."In this article, we present a number of open problems from the theory of semifeasible algorithms. For each we present its background and review what partial results, if any, are known.
