Alright... after switching things the wrong way i've switched them right :)

Due to this :

  vector<float> solution = reference_solutions(34,34 , grd);
  vector<float> test = users_solution(34, 34, grd);
  Assert::That(solution.at(c), EqualsWithDelta(test.at(c), .0001));

In error messages, the actual and expected are swapped.

:D

Thanks for pointing that out... fixed it.

In full test suite:

main.cpp:101:5: error: use of undeclared identifier 'init_bool_grid'
    init_bool_grid(n, m, checked);
    ^

When I am checking all possible paths then sometimes I have got a little better result than in tests.
Are the test correct for sure?

Although my comment above focuses on the negative, personally, I think that this is a good kata because it gives a real-world situation for doing the dot product. There are many ways to do a dot product, so it gives us practice thinking about it.

As it is, some people are challenged not by the underlying problem itself, but by the description of the problem. I like that example, @Chrono79, and think that it could strengthen the description.

Alternately, you could just write it out in words.

Each race has a certain worth when battling against others.

That should cover the common error, but if a test was added in the sample tests it would be fine by me. Or adding this example to the description:

     Good                                       Evil

 0 0 0 0 0 1                   /            0 0 0 1 1 1 0
    Wizard                     /       Goblin + Uruk Hai + Troll
      10                       /         2    +  3       +   5
      10                       /               10                           

10 = 10 therefore it is a draw

Maybe it's just "Evil", not bad!

a bad kata!!!

The tests, as they currently stand, need serious rewriting:

• there are no random tests
• Test.expect should be changed to Test.assertEquals to see what our function has returned
• The test message should (probably) also show the inputs

(Also, if anyone wants to raise another issue about test cases being wrong, don't do it unless you can show why. Otherwise they're bogus and just noise.)

Not an issue
