/* Computes the product of two unsigned fixed-point 8-bit values from 0 to 1

* Jim Blinn gives multiple ways to compute this in "Jim Blinn's Corner:
* Notation, Notation, Notation", the first of which is
*
* prod(a, b) = (a * b + 128) / 255.
*
* By approximating the division by 255 as 257/65536 it can be replaced by a
* multiply and a right shift. This is the implementation that we use in
* pix_multiply(), but we _mm_mulhi_pu16() by 257 (part of SSE1 or Extended
* 3DNow!, and unavailable at the time of the book's publication) to perform
* the multiplication and right shift in a single operation.
*
* prod(a, b) = ((a * b + 128) * 257) >> 16.
*
* A third way (how pix_multiply() was implemented prior to 14208344) exists
* also that performs the multiplication by 257 with adds and shifts.
*
* Where temp = a * b + 128
*
* prod(a, b) = (temp + (temp >> 8)) >> 8.

Author: Jake Bringewatt
Use: Finds the ground state and first excited state candidate in the sigma = 0 subspace, and one of the n-1 degenerate first excited state candidates in the sigma=1 (sigma_1=0, sigma_2=1 or sigma_1=1, sigma_2=1) subspace for two Hamming symmetric wells. Takes a standard input file which is for a Hamming spherical potential with constant strength. Can easily be generalized to more complicated potentials.
Wells except the first well listed in this file will be given a schedule of b(s)=1-s instead of b(s)=s. Used for doing a Grover with priors problem as in example 1 of the paper.
Dependencies: Lapack, Blas
Compile: gcc -o TwoWellSolver_GroverWithPriors ./TwoWellSolver_GroverWithPriors -lm -lblas -llapack
Run: ./TwoWellSolver_GroverWithPriors wellInputFile paramInputFile
Input:
Standard well input file (see README) [wellInputFile]:
Has the standard form for all codes:
number of qubits
number of wells (will return with error if not 2)
well depth (double)(<0)
well width (integer)(in [1,n])
e.g.
10
2
-2.1
1
-2
2
One well solver parameter input file [paramInputFile]:
Gives relevant parameters for this code:
runname - tag for output filenames
include wfs - 0 if no wfs desired, 1 if wfs desired
sList - 0 if want to telescope, 1 if want to print for a specific list of s, if 1 follow by a list of s values to run problem at
if 0 next two lines are:
numSteps - number of steps in s per range scanned over (recommended to be 10*k+1 for some integer k)
iMax - maximum number of loops through telescoping procedure
telescopeParam - 0 for gap within sig=0, 1 for max of 2 possible gaps, 2 for min of 2 possible gaps
if 1 next lines are list of s values to solve at
e.g
testRun1
1
0
21
10
or,
testRun2
0
1
0.0
0.1
0.2
0.25
0.30
0.5
0.7
....
Output: 2 csv files:
1. runname.ow.energies.output
Gives the energies and gaps at each s where each row is
s, E0 (sigma=0), E1 (sigma=0), E1*(sigma=1), E1-E0, E1*-E0
2. runname.ow.wfs.output
For each s gives the following n+1 rows
E0 Wf
E1 Wf
E1* (gamma=0) Wf (same for all gamma)
