The algorithm uses NLP, SBERT semantic similarity, TF-IDF, and integer programming constraint optimisation to match people and then introduce to each other based on their profiles.

The assignments are computed based on persons' profile similarity and at the same time by considering that personal availability is not an infinite resource. By balancing these two contradicting aspects using a risk-averse strategy the algorithm maximises the satisfaction of everybody as equally as possible.

Enables one to search for multi-leg trips for travelling between farther distances, like St. Petersburg and Budapest.
TSolutions is a ticket sales software used by both Estonian local bus transport companies and also by companies offering international travels, like Transdev, Nettbuss, LuxExpress, Tallinn Coach Station, Cargobus and others.
Current algorithm became first in use in LuxExpress ticket sales website and cashier systems.

We are building a novel kind of Windows software called Green Wave, which intelligently reduces and manages the resource use of background programs. As a result the work on computer is smoother and more responsive, providing better user experience, the user can save time, and the energy use is smaller. The computer is quieter, the temperature is lower, and battery lasts longer.

Completed: Beta version in April 2014

StaffLogic is manpower planning software developed by Nortal (former WebMedia).
Simplify's responsibility in that project was designing and developing the algorithm for forecasting work load / demand at different time points in servicing facilities like bank branches, call centres and supermarkets.

The compression algorithm was written as subcontract work for Webmedia who needed it for participating in a public procurement. Webmedia also won that procurement. The efficiency of compression was marked as one of the most important criteria for selecting the winner.
The algorithm uses differential encoding, solid compression and universal codes. In demo version it was able to compress page-long reports to about 7-byte long short messages for sending them from the fishing boats over the costly satellite link.
With the compression algorithm accompanies also an application specific protocol layer which ensures the reliable delivery of the data.

StaffLogic is manpower planning software developed by Nortal (former WebMedia).
Simplify's responsibility in that project is designing and developing the algorithm for automatic work schedule planning, that is - solving the so-called "timetabling problem" as optimally as possible. That kind of problems belong to the NP-hard complexity class - which means in laymans terms computationally "intractable problems".
Breakthrough in solving the problem was achieved when we engineered a specially tailored algorithm - local search.
The algorithm must consider the competences of employees, different restrictions written in law regarding the work time, nightwork time and free time. It also must consider the hourly rates of employee salaries, eployees' personal preferences, allow each employee to have alternating types of assignments, avoid under- and overhours, and it has to prevent employees from losing their competences due to competence underhours. Finally, it should try to treat every employee as equally as possible.
The algorithm will be used for managing work schedules of teams consisting of hundreds of employees. Currently it is used by Estonian Air Navigation Services LTD and Securitas LTD, and is being installed in Estonian Energy LTD, multiple other orders are pending.

It is an Excel Macro Program which enables the user to conveniently compare two different but similar and voluminous price lists. The software helps one to find out what has changed in the new price list as compared to the old one, what has been removed and which new entries have been inserted. The software highlights changed areas and uncovers the types of the changes.
