Our Journals did not have any Fees or Article Processing Charges from 2002 until 2015 though they were OA (Open Access) since January 1st of 2007.
After 2015, WSEAS imposed some Fees or Article Processing Charges, but for authors publishing in WSEAS Transactions, WSEAS offered and offers waivers and discounts in cases of quality scientific research or in cases that the authors are not in a position to cover the APCs, because they do not receive financial support from their universities/institutions or they come from developing countries.
From 2015 to present (2021) more than 70% of the authors in WSEAS transactions published their paper withour payment of APCs in some of ur Journals. WSEAS provides waivers and discounts to the authors that have excellent scientific work to present or to the authors that are not in a position to pay their Fees or Article Processing Charges. However some times WSEAS can change the journal for publication informing the authors in advance in order to provide them better fees or free publication. No paper can be deleted from our web site after the publication for any reason.
Invited papers by Editors-in-Chief, Associate Editors, Assistant Editors are always exempted from APC (Article Processing Charge). These authors must send their papers only by EMAIL, in order to avoid Article Processing Charges!

Corrections, after the online publication, for errors that are not due to WSEAS Secretariat and to our WebMaster are subject to fees: 100 EUR per page that the authors ask for correction.
