Maximizing Chocolates in Grid using 2 robots


In this article, we dive into the methodologies and calculations utilized actually to handle this issue.

In mechanical technology and improvement issues, boosting chocolates in a matrix utilizing two robots presents a charming test. This situation includes effectively exploring a network to gather as many chocolates as possible, however, under the circumstances of utilizing two robots with characterized capacities. Such issues track down applications in different fields, including stockroom computerization, coordinated factors, and, surprisingly, gaming procedures.

Understanding the Problem

Envision a matrix where every cell addresses a vacant space or a chocolate. Two robots are put on this matrix, each fit for moving in four bearings: up, down, left, and right. The goal is to boost the quantity of chocolates these robots gather while exploring through the network. The robots can't possess a similar cell all the while, and they can get chocolates in their ongoing cell.

Strategies and Algorithms:

A few procedures and calculations can be applied to tackle the issue of boosting chocolates in the matrix utilizing two robots. One such methodology is a variety of Depth-First Search (DFS) joined with Dynamic Programming.

1. Depth-First Search (DFS):

DFS is a crucial calculation for crossing or looking through tree or diagram information structures. In this situation, DFS can be applied to investigate all potential ways the robots can take while gathering chocolates. The calculation investigates every way recursively, backtracking when essential.



DFS starts at the upper-left corner.

It investigates neighboring cells recursively, going either right or down.

If it encounters a dead end, it returns and investigates other viable choices.

DFS repeats this procedure until it reaches the bottom right corner, gathering chocolates along the way.

  • The DFS capability dfs investigates all potential ways the robots can take while gathering chocolates.
  • At each step, it thinks about moving in four headings: up, down, left, and right.
  • It recursively investigates each substantial move, refreshing the quantity of chocolates gathered.
  • The isValidMove capability checks, assuming the move is inside the network limits.
  • The primary capability instates the network and beginning places of the two robots and summons the DFS capability to find the most extreme number of chocolates gathered.

2. Dynamic Programming

Dynamic Programming can be utilized to streamline the DFS approach by remembering subproblems and keeping away from repetitive calculations. By putting away the consequences of subproblems in a table, Powerful Programming guarantees that each subproblem is settled just a single time, fundamentally diminishing the time intricacy of the calculation.


Consider a little 3x3 grid filled with chocolates of different values:


Using dynamic programming, we determine the maximum number of chocolates that may be gathered, beginning with each cell and progressing to the bottom-right corner.

We fill in a table with these maximum values, taking into account each chocolate's value as well as the maximum values collected from neighboring cells.

Following the values in the table, we estimate the best path for each robot to collect chocolates, ensuring that they collect as many as feasible.

  • The maxChocolates technique introduces the DP exhibit and starts the DFS search from the upper left corner of the lattice (position (0, 0) for the principal robot and (0, 0) for the subsequent robot).
  • The dfs technique recursively investigates all potential moves for the two robots, keeping away from impacts and out-of-bound positions.
  • At each step, it figures the most extreme number of chocolates gathered by picking the best move.
  • The DP exhibit dp is utilized to store the most extreme chocolates gathered at each place of the two robots to stay away from repetitive computations.
  • At long last, the fundamental strategy introduces the framework and prints the most extreme number of chocolates gathered by the two robots.

3. Greedy Algorithms

Greedy Algorithms can likewise be utilized, where the robots settle on locally ideal decisions at each step with the expectation of viewing as a worldwide ideal. Finding an ideal avaricious procedure for this issue may be trying because of the mind-boggling nature of the matrix and the cooperation between the robots.

Let's illustrate this with an example:

Consider the same grid:

The greedy algorithm starts in the upper-left corner.

At each stage, it selects the neighboring cell with the greatest chocolate value.

It continues to make greedy decisions until it reaches the bottom right corner.

However, the greedy algorithm's path may not result in the highest overall worth of chocolates acquired since it just analyses current options without looking forward or considering the cumulative impact of its selections.

A potential greedy strategy could be:

  • At each step, the two robots move towards the closest chocolate.
  • Assuming that numerous chocolates are equidistant, every robot chooses the nearest chocolate to it.

  • In this Greedy algorithm execution, we over and over move every robot towards the closest chocolate.
  • We ascertain the Manhattan distance from every robot to all chocolates and move every robot towards the nearest one.
  • This interaction goes on until no more chocolates are reachable.
  • The robots pursue choices dependent exclusively upon the prompt circumstance, disregarding future results broadly, expecting to expand the number of chocolates gathered at each step.


Boosting chocolates in a lattice utilizing two robots gives a captivating enhancement issue with different potential methodologies. By utilizing systems like DFS, Dynamic Programming,and greedy algorithms, it is feasible to foster productive calculations to take care of this issue. These calculations track down applications in advanced mechanics and robotization as well as in different areas where asset improvement is essential. As innovation propels, further innovative work in this space vows to yield significantly more modern answers for such difficulties.
