the loop can be simplified to only compute one of the inverses instead of all of them:

**Define** *ElligatorSwift(x)* as:
* Loop:
  * Pick a uniformly random field element $u.$
  * Pick a uniformly random integer $c$ in $[0,8).$
  * Let $t = G_{c,u}(x).$
  * If $t \neq \bot$, return $(u, t)$; restart loop otherwise.

This is implemented in `secp256k1_ellswift_xelligatorswift_var`.

libsecp256k1/doc/ellswift.md  view on Meta::CPAN

And the x-only ElligatorSwift encoding algorithm is still:

**Define** *ElligatorSwift(x)* as:
* Loop:
  * Pick a uniformly random field element $u.$
  * Pick a uniformly random integer $c$ in $[0,8).$
  * Let $t = G_{c,u}(x).$
  * If $t \neq \bot$, return $(u, t)$; restart loop otherwise.

Note that this logic does not take the remapped $u=0$, $t=0$, and $g(u) = -t^2$ cases into account; it just avoids them.
While it is not impossible to make the encoder target them, this would increase the maximum number of $t$ values for a given $(u, x)$

libsecp256k1/doc/ellswift.md  view on Meta::CPAN

* Let $w' = w$ if $sign(w/2) = sign(y)$; $-w$ otherwise.
* Depending on $c:$
  * If $c \in \\{0, 2\\}:$ return $P_u^{'-1}(v, w').$
  * If $c \in \\{1, 3\\}:$ return $P_u^{'-1}(-u-v, w').$

Note that $c$ now only ranges $[0,4)$, as the sign of $w'$ is decided based on that of $y$, rather than on $c.$
This change makes some valid encodings unreachable: when $y = 0$ and $sign(Y) \neq sign(0)$.

In the above logic, $sign$ can be implemented in several ways, such as parity of the integer representation
of the input field element (for prime-sized fields) or the quadratic residuosity (for fields where
$-1$ is not square). The choice does not matter, as long as it only takes on two possible values, and for $x \neq 0$ it holds that $sign(x) \neq sign(-x)$.

libsecp256k1/doc/ellswift.md  view on Meta::CPAN

* Let $Y = \dfrac{X + t''}{u'\sqrt{-3}}.$
* Let $x$ be the first element of $(u' + 4Y^2, \frac{-X}{2Y} - \frac{u'}{2}, \frac{X}{2Y} - \frac{u'}{2})$ for which $g(x)$ is square.
* Let $y = \sqrt{g(x)}.$
* Return $(x, y)$ if $sign(y) = sign(t)$; $(x, -y)$ otherwise.

This is implemented in `secp256k1_ellswift_swiftec_var`. The used $sign(x)$ function is the parity of $x$ when represented as in integer in $[0,q).$

The corresponding encoder would invoke the x-only one, but negating the output $t$ if $sign(t) \neq sign(y).$

This is implemented in `secp256k1_ellswift_elligatorswift_var`.

Note that this is only intended for encoding points where both the x-coordinate and y-coordinate are unpredictable. When encoding x-only points
where the y-coordinate is implicitly even (or implicitly square, or implicitly in $[0,q/2]$), the encoder in
[Section 3.5](#35-encoding-for-secp256k1) must be used, or a bias is reintroduced that undoes all the benefit of using ElligatorSwift
in the first place.
