Introduction

The world of photography in Indonesia is rapidly growing, with many people becoming interested in this field. To study photography, it is essential for individuals to understand the terms that exist. However, the traditional method of using printed term dictionaries can be time-consuming and inefficient. The development of an Android-based photography dictionary application using the Quick Search and Optimal Mismatch algorithms can provide a more efficient and modern way of learning photography terms.

Background

The development of an Android-based photography dictionary application is a response to the need for a more efficient and modern way of learning photography terms. The application is designed to utilize the Quick Search and Optimal Mismatch algorithms to speed up the process of finding photography terms. The Basic4Android software and visual basic programming language are used to develop the application, while SQLite is used as the database management system.

The Quick Search Algorithm

The Quick Search algorithm is a popular algorithm used for searching strings. It works by comparing the search string with the terms in the dictionary and returning the first match found. The algorithm has a time complexity of θ (Mn), where n is the length of the search string and m is the length of the term being searched. However, the Quick Search algorithm can be slower when searching for simpler or more common terms.

The Optimal Mismatch Algorithm

The Optimal Mismatch algorithm is designed to find errors in searching that can occur during the string matching process. By optimizing the way of searching, this algorithm is able to minimize the time needed to find the term sought. The algorithm works by not checking every character in the search string, but immediately jumping over the parts that are clearly irrelevant. This makes the Optimal Mismatch algorithm faster than the Quick Search algorithm.

Comparison of the Two Algorithms

The results of the comparison between the Quick Search and Optimal Mismatch algorithms showed that the Optimal Mismatch algorithm is superior in terms of speed. The average process time (running time) for the Optimal Mismatch algorithm is 8.5 ms, while for the Quick Search algorithm is 11.5 ms. Although both algorithms have the same complexity, namely θ (Mn), their effectiveness in terms of search time is significant.

Advantages of the Optimal Mismatch Algorithm

The Optimal Mismatch algorithm has several advantages over the Quick Search algorithm. Firstly, it is faster in terms of search time. Secondly, it is more efficient in terms of memory usage. Finally, it is more robust in terms of handling errors in the search string.

Comparison with the Quick Search Algorithm

The Quick Search algorithm is also known to have good performance, especially in situations where the search patterns are longer. However, this algorithm tends to be slower when searching for simpler or more common terms. This weakness can be a problem in the dictionary application that is intended to provide information quickly.

Impact of Application Usage

The existence of an Android-based photography dictionary application that utilizes the Optimal Mismatch algorithm can have a significant impact on users. Users can get information quickly and efficiently, which will certainly improve user experience and save their time in learning photography. This application is expected to be a practical solution for people who want to deepen their understanding of the terms in photography without having to depend on print books that take time.

Conclusion

The development of an Android-based photography dictionary application using the Optimal Mismatch and Quick Search algorithms indicates that using the right algorithm, the information search process can be done more efficiently. The results showing the advantage of the Optimal Mismatch algorithm can be the basis for developing further applications and encouraging public interest in learning photography in a more modern way.

Recommendations

Based on the results of this study, the following recommendations can be made:

  1. The Optimal Mismatch algorithm should be used in the development of dictionary applications to improve search time and efficiency.
  2. Further research should be conducted to compare the performance of the Optimal Mismatch algorithm with other algorithms.
  3. The application should be developed to include more features, such as image recognition and augmented reality, to improve user experience.

Limitations

This study has several limitations. Firstly, the study only compared the performance of the Optimal Mismatch algorithm with the Quick Search algorithm. Secondly, the study only used a small dataset of photography terms. Finally, the study did not consider the impact of user interface and user experience on the performance of the application.

Future Research Directions

Future research directions include:

  1. Comparing the performance of the Optimal Mismatch algorithm with other algorithms, such as the Knuth-Morris-Pratt algorithm and the Rabin-Karp algorithm.
  2. Developing a more comprehensive dataset of photography terms to improve the accuracy of the results.
  3. Investigating the impact of user interface and user experience on the performance of the application.
