Sequential search starts at the beginning of the list and checks every element of the list. Sequential search is also called as Linear Search. We also find that refinement tools lead to a less concentrated market structure. To search an element in a given array, it can be done in following ways: 1. As a real world example, pickup the nearest phonebook and open it to the first page of names. In contrast, if the website simply informs consumers that the default ranking already reflects product popularity, quality, or relevance, consumers search less and their surplus improves. One of the most straightforward and elementary searches is the sequential search, also known as a linear search. Consequently, overall consumer surplus may deteriorate when total search cost outweighs the enhanced utility. When consumers are unaware of such default ranking rules, they may engage in disproportionately more searches using refinement tools. This makes both the time complexities the same. if element Found at last O (n) to O (1) It is the same as the previous method because here we are performing 2 ‘if’ operations in one iteration of the loop and in the last method we performed only 1 ‘if’ operation. Assuming that the record you are searching for exists in the file exactly once and could be anywhere in the file with equal probability, the average number of comparisons is equal to half the number of records in the file. Improve Linear Search Worst-Case Complexity.
Most websites by default rank search results according to their popularity, quality, or relevance to consumers (e.g., Google). A sequential search starts from the beginning of the file and checks each element one-by-one until the desired element is found. We find that the refinement tools encourage 33% more searches and enhance the utility of purchased products by 17%. The results show that refinement tools have significant effects on consumer behavior and market structure. The model is instantiated using consumer click-stream data of online hotel bookings provided by a travel website. The proposed model can integrate consumers’ decisions of search and refinement. The index is searched 1st then the array and guides the search in the array. Each element in the index points to a block of elements in the array or another expanded index. In case of ordered arrays, the method of binary search is much. This implementation uses a singly linked list and sequential search. This method is used when the array is not an ordered array. Furthermore, one important feature of online search technology is that it gives consumers the ability to refine search results using tools such as sorting and filtering based on product attributes. In Indexed Sequential Search a sorted index is set aside in addition to the array. It does not call either the compareTo() or hashCode() method. Because such exclusion restrictions are often available in online click-stream data, the identification and corresponding estimation strategy is generalizable for many online shopping websites where such data can be easily collected.
Our identification of the search model relies on exclusion restriction variables that separate consumer utility and search cost.

Applications of Linear Search: Linear search is rarely practical because other search algorithms and schemes, such as the binary search algorithm and hash tables, allow significantly faster searching for all but short lists.
