+  An implementation of a steepest descent solver for binary quadratic
+models.
+
+  Steepest descent is the discrete analogue of gradient descent, but
+the best move is computed using a local minimization rather rather
+than computing a gradient. At each step, we determine the dimension
+along which to descend based on the highest energy drop caused by a
+variable flip.
+
+
+  Optional building mode set with environment variables:
+  - TESTS=yes (performs tests, requires dimod)

+# HOW TO EDIT THIS FILE:
+# The "handy ruler" below makes it easier to edit a package description.
+# Line up the first '|' above the ':' following the base package name, and
+# the '|' on the right side marks the last column you can put a character in.
+# You must make exactly 11 lines for the formatting to be correct.  It's also
+# customary to leave one space after the ':' except on otherwise blank lines.
