A Guide to OptaPlanner 1. Introduction to OptaPlanner In this tutorial, we look at a Java constraint satisfaction solver called OptaPlanner. OptaPlanner solves planning problems using a suite of algorithms with minimal setup. Although an understanding of the algorithms may provide helpful detail, with the framework performing the hard work for… Continue Reading opta-planner

Logistic Regression in Java 1. Introduction Logistic regression is an important instrument in machine learning (ML) practitioner toolbox. In this tutorial, we’ll explore the main idea behind logistic regression. First, let’s start with a brief overview of ML paradigms and algorithms. 2. Overview ML allows us to solve problems that… Continue Reading java-logistic-regression

Find the Middle Element of a Linked List 1. Overview In this tutorial, we’re going to explain how to find the middle element of a linked list in Java. We’ll introduce the main problems in the next sections, and we’ll show different approaches to solving them. 2. Keeping Track of… Continue Reading java-linked-list-middle-element

Counting Sort in Java 1. Overview General-purpose sorting algorithms like Merge Sort make no assumption about the input, so they can’t beat the O(n log n) in the worst case. Counting Sort, on the contrary, has an assumption about the input which makes it a linear time sorting algorithm. In this… Continue Reading java-counting-sort

How to Find the Kth Largest Element in Java 1. Introduction In this article, we’ll present various solutions for finding the kth largest element in a sequence of unique numbers. We’ll use an array of integers for our examples. We’ll also talk about each algorithm’s average and worst-case time complexity.… Continue Reading java-kth-largest-element

Creating a Triangle with for Loops in Java 1. Introduction In this tutorial, we’re going to explore several ways to print a triangle in Java. There are, naturally, many types of triangles. Here, we’re going to explore only a couple of them: right and isosceles triangles. 2. Building a Right… Continue Reading java-print-triangle
