produced an interesting

post</a> on
<a href="https://github.com/eclipse/eclipse-collections";>Eclipse
Collections</a> this one shows some code for modelling and manipulating cards
with Java 17 and Eclipse Collections. His related katas are highly recommended.

We recently released versions 4.0.4, 3.0.12 and 2.5.18 with 42, 21 and 15 fixes
and improvements respectively. Two quick highlights for the 4.0.4 release
before getting into more details about the release.</p>

+<p>Let’s look at solving this programmatically using Groovy.

Hipparchus</h2>
+<div class="sectionbody">
+<div class="paragraph">
+<p>Let’s now look at solving this problem using a simplex solver.
+We’ll use the <code>SimplexSolver</code> class from Apache Commons
+Math which is essentially the same as the one from Hipparchus
+(a commons math fork).</p>
+</div>
+<div class="paragraph">
+<p>We’ll start with a little helper method for defining our
constraints:</p>
+</div>
+<div class="listingblock">
+<div class="content">
+<pre class="prettyprint highlight"><code data-lang="groovy">static
scalar(coeffs, rel, double val) {
+ new LinearConstraint(coeffs as double[], rel, val)
+}</code></pre>
+</div>
+</div>
+<div class="paragraph">
+<p>Next we define our individual constraints and the combined set:</p>
+</div>
+<div class="listingblock">
+<div class="content">
+<pre class="prettyprint highlight"><code data-lang="groovy">var milk_max =
scalar([0, 1, 0, 0, 0, 0], LEQ, 1)
+var fish_min = scalar([0, 0, 0, 0, 1, 0], GEQ, 0.5)
+var protein = scalar([4.0, 8.0, 7.0, 1.3, 8.0, 9.2], LEQ, 10)
+var fat = scalar([1.0, 5.0, 9.0, 0.1, 7.0, 1.0], GEQ, 8)
+var carbs = scalar([15.0, 11.7, 0.4, 22.6, 0.0, 17.0], GEQ, 10)
+var calories = scalar([90, 120, 106, 97, 130, 180], GEQ, 300)
+
+LinearConstraintSet constraints = [milk_max, fish_min, protein, fat, carbs,
calories]</code></pre>
+</div>
+</div>
+<div class="paragraph">
+<p>Each individual constraint has a coefficient for each food,
+a relationship, and a value.</p>
+</div>
+<div class="paragraph">
+<p>Next, we define our cost function, and an additional constraint
+to indicate that we can’t buy a negative amount of any food.
+The <code>zeroOrMore</code> constraint saves us from doing the long-hand
+equivalent, like <code>fish_min</code> but with a minimum of <code>0</code>,
for each food.</p>
+</div>
+<div class="listingblock">
+<div class="content">
+<pre class="prettyprint highlight"><code data-lang="groovy">var cost = new
LinearObjectiveFunction([2.0, 3.5, 8.0, 1.5, 11.0, 1.0] as double[], 0)
+
+var zeroOrMore = new NonNegativeConstraint(true)</code></pre>
+</div>
+</div>
+<div class="paragraph">
+<p>Now, our solution is found by creating a new solver, and asking
+it to optimize using our cost function and the constraints.
+We then print our solution out:</p>
+</div>
+<div class="listingblock">
+<div class="content">
+<pre class="prettyprint highlight"><code data-lang="groovy">var solution = new
SimplexSolver().optimize(cost, constraints, zeroOrMore)
+
+static pretty(int idx, double d) {
+ d ? [sprintf('%s %.2f', ['🍞', '🥛', '🧀', '🥔', '🐟', '🍶'][idx], d)] : []
+}
+
+if (solution != null) {
+ printf "Cost: %.2f%n", solution.value
+ println solution.point.indexed().collectMany(this::pretty).join(', ')
+}</code></pre>
+</div>
+</div>
+<div class="paragraph">
+<p>When run, it gives the following output:</p>
+</div>
+<div class="listingblock">
+<div class="content">
+<pre>Cost: 12.08
+🥛 0.05, 🧀 0.45, 🥔 1.87, 🐟 0.50</pre>
+</div>
+</div>
+<div class="paragraph">
+<p>This is the same solution as what we saw when using the spreadsheet.</p>
+</div>
+<div class="paragraph">
+<p>You can currently swap between Apache Commons Math and Hipparchus
+by switching the Maven coordinates of the jar being used on the classpath
+and changing a few import statements. This may change in future versions,
+but for now:</p>
+</div>
+<div class="ulist">
+<ul>
+<li>
+<p>Using <code>org.apache.commons:commons-math3:3.6.1</code> gives an older
stable version
+of Commons Math, starting to show its age at 8 years old.</p>
+</li>
+<li>
+<p>Using <code>org.apache.commons:commons-math4-legacy:4.0-beta1</code>
+gives the latest version of these classes from Apache Commons Math.
+The naming possibly deserves some explanation. There has been ongoing
+effort to modularise Commons Math and there are numerous components
+delivered as a result. The optimisation classes haven’t
+been worked on yet and are available in the aforementioned artifact.</p>
+</li>
+<li>
+<p>Using <code>org.hipparchus:hipparchus-optim:3.0</code> gives classes from
the forked
+project. For the classes we are using, there is essentially no difference
+in the fork, but other parts of the library have seen useful updates
+if you don’t mind having a dependency that isn’t backed by the
ASF.</p>
